Ridge-tailed Monitor

Varanus-acanthurus-range.jpg

Varanus acanthurus or Ridge tailed Monitor

The Ridge tailed monitor is one of Australia's smaller Monitor species, growing to only 78 cm long, most of which is tail. They are found in the desert areas in Queensland, the Northern Territory, and Western Australia. Their diet includes grasshoppers, cockroaches and beetles. The scales on the tail of the Ridge Tailed monitor are raised and pointed, hence its common name. This helps the monitor anchor itself in the rock crevices it calls home. This anchoring makes it impossible for hungry predators to extract and eat the lizards.

As with all Monitors the females lay eggs. Ridge tailed Monitor usually lay 4 to 8 eggs per clutch. The female lays her eggs in a nest chamber at the end of a tunnel she's dug into sandy soil. Monitors are more active than most other reptiles, and as such they like to have a higher body temperature. You'll often see monitors basking in the sun on the side of roads, which can unfortunately lead to their untimely demise.

Rough-scaled Snake

Tropidechis-carinatus-range.jpg

Tropidechis carinatus or Rough scaled Snake

Rough scaled snake is often confused with the harmless Keelback Snake. Both have rough scales that help them to climb. The Rough scaled snake has relatively long fangs, and a highly neuro-toxic venom. Recipients of a Rough scaled Snake bite often fall into unconsciousness within minutes of being bitten. Rough scaled Snake is closely related to the Tiger Snake group, and Tiger Snake anti-venom will effectively neutralize their venom.

The Rough scaled Snake species grow up to about 1 metre. They're one of the few venomous Australian snakes that can regularly be found climbing trees.

To locate their prey a rough scaled snake will actively hunt, or wait to ambush, any small mammals, frogs, birds, or reptiles they can find. As with virtually all snakes, it is a shy, nervous creature that would rather flee than fight, but if provoked it can become quite aggressive. From 5 to 18 large, live young are produced every second year.

Thick-tailed Gecko

Underwoodisaurus-milii-range.jpg

Underwoodisaurus milii or Thick tailed Gecko

The thick tailed gecko inhabits many environments including wet and dry sclerophyll forest, open grasslands, scrubland and even desert, particularly those areas associated with rock outcrops. It is found in south-east Queensland, and extends down over much of southern Australia except the far southeast and southwest. It is often found in backyards, sheltering under logs and rocks. Its scientific name (Underwoodisaurus) isn't referring to where this gecko likes to shelter. Rather, it is named after a Mr Underwood, with Underwoodisaurus meaning 'Underwood's lizard'.

If threatened, the Thick tailed Gecko raises itself up on its skinny legs, waves its tail from side to side and lunges at the threat producing a croaky barking sound at the same time, hence its other common name of barking gecko. As with other geckos, only two eggs are produced at a time, usually in spring or early summer. Several clutches may be produced during good seasons, with about a month's interval between each. The eggs incubate for approximately two and a half months before they hatch.

Slaty-grey Snake

Stegonotus-cucullatus-range.jpg

Stegonotus cucullatus or Slaty grey Snake

The non-venomous Slaty grey Snake is found on Cape York Peninsula of North Queensland and the northern part of the Northern Territory. They feed on fishes (including eels), tadpoles, frogs, lizards, reptile eggs and small mammals. When feeding on small mammals, the Slaty grey Snake constricts its prey in a python-like fashion. When hunting they will happily climb into low shrubs or rocky banks in the vicinity of frog breeding sites.

If cornered or grasped Slaty grey snake will respond by biting repeatedly and emitting a pungent, unforgettable odour. The female is an egg layer. These snakes are found in coastal plains and dunes, watercourses, slopes and ranges in tropical shrublands, woodlands and forests, including rainforests. They are normally found near swamps, billabongs and water courses that contain frogs and small fish.

Pebble Dragon

Tympanocryptis-cephalus-range.jpg

Tympanocryptis cephalus or Pebble Dragon

This truly earless pebble dragon has large pale blotches across the top and side of its tail. It feeds on small insects and while normally active during daylight hours, it has been known to be active on warm nights. The males of this species tend to be slightly smaller than the females, but they have longer hind legs.

Pebble Dragon can be found in tropical to temperate tablelands, slopes and plains with lots of rocks on the ground. The short, fat body of this lizard, combined with its colouration, allow it to blend in with the surrounding rocky ground. The scientific name of this lizard's genus (Tympanocryptis) means 'hidden ear'.

Eastern Brown Snake

Pseudonaja-textilis-range.jpg

Pseudonaja textilis or Eastern Brown Snake

This is a large, diurnal (active during the day), dangerously venomous snake. We often get carried away with the potency of a snake's venom, but the distribution and temperament of the animal is also an issue. In the last decade the Eastern Brown Snake has become the cause of most snakebite deaths in Australia. This is not because these animals are more aggressive - quite the contrary. When an Eastern Brown Snake is confronted it will lunge at the aggressor out of fear.

The Eastern Brown Snake increased its numbers thanks to man, due primarily to an increase in prey items. Mice and rats are a favourite food, and the increased numbers of these inhabiting rubbish left by humans provide more than enough food for these snakes. They will also happily consume lizards and frogs.

The Eastern Brown Snake is perhaps the most important species of snake from a medical point of view. Textilinin is a derivative of this animal's venom. Textilinin is an inhibitor of plasmin, which is important in dissolving blood clots. Inhibiting plasmin with agents like Textilinin can be used to stop bleeding during major surgery. The Eastern Brown Snake is another snake that is often not true to its name in colour, with shades of brown, grey and black being as common as plain brown. Juveniles can be speckled with orange and are very pretty. Females are egg layers, producing up to 24 eggs.

Eastern Blue-tongued Skink

Tiliqua-scincoides-range.jpg

Tiliqua scincoides or Eastern Blue-tongued Skink

Eastern Blue-tongued Skink is common throughout Eastern Australia, often found in bushland and suburban areas where conditions are suitable. They are known as blue-tongues because their tongue ranges from bright to dark blue, and they have a habit of displaying it prominently and hissing loudly when disturbed.

The Eastern Blue-tongued Lizard is a stout and slow lizard that grows up to 30-60 cm in length, with brown to grey scales and a barred pattern across the body and tail. The underside is usually pale. Blue-tongued skink Lizards are popular as pets and can live for up to 30 years in captivity.

Eastern Blue-tongued Skink give birth to live young, between six to a record twenty per litter. Young Eastern Blue-tongued Skink can consume the egg sac immediately after birth.

Western Brown Snake

Pseudonaja-nuchalis-range.jpg

Pseudonaja nuchalis or Western Brown Snake

Western brown snake can be found over most of mainland Australia, being noticeably absent from the moister areas of the east, south east and south western Australia. Western Brown Snake shelter in disused mammal burrows and deep soil cracks, and under fallen timber and rocks. During warmer weather these snakes become nocturnal. They feed on small mammals, birds and reptiles, including other snakes.

Western Brown Snake species includes 12 to 16 colour variations, some of which may turn out to be different species. The phylogenetic relationships of the brown snake group are still being investigated. It may turn out that this black-headed form of the western brown snake is actually a separate species. 9 to 38 eggs are laid in a clutch from November to January. Once the babies hatch they are completely self-sufficient, and are capable of delivering a dangerously venomous bite to humans.

Shingleback Lizard

Tiliqua-rugosa-range.jpg

Tiliqua rugosa or Shingleback Lizard

A close relative of the more familiar bluetongue, the shingleback lizard is an extremely distinctive member of the lizard family known as skinks. Its two most striking features are the short rounded tail, which bears a remarkable resemblance to the head end to confuse predators and the huge scales covering the body giving it a rough and bumpy appearance. Like its close relative, the Shingleback Lizard has a large tongue, which is fleshy and dark blue in colour and used to warn off any potential threats such as dingoes or foxes. An adult shingleback lizard is robust lizards with a broad, triangular head. A large adult will measure over 35cm in length.

Shingleback lizard appear to have more common names than any other Australian animal. It seems every region in this animal's distribution has its own preferred name. Apart from shingleback, others names include sleepy lizard, bobtail, pinecone lizard, stumpy-tail, boggi and double-headed lizard. Most of the diet is made up of vegetable matter including foliage, berries and fruits. They have a particular liking for flowers and will seasonally gorge themselves on blossoms, particularly yellow ones, if given the opportunity. The occasional insect, spider or scorpion is also eaten.

Childrens Python Breeding

by Matt & Nicci Turner

Despite confusion over its name, the small and easily kept Antaresia childreni is a snake for all.

We think that most biologists, ecologists, paleontologists and other scientists have daydreamed at one point or another of having the honor of being immortalized with the assignment of their surname to describe an organism to science. What a great thing it would be to be among the scientists who have plants and animals named after them -- the D'Albert's python, the Bibron gecko, the Colett's black snake and others. But to what benefit would that honor be to the understanding of the plant or animal? It is neither descriptive nor geographic, and as is the case for Antaresia childreni, often confusing or misleading.

Childrens Python: A Problematic Honor

In naming new species, it was once common to recognize an individual who acted as a mentor or who has had a profound impact to the scientific development and maturation of the person giving the official description. Unfortunately, this great honor is usually only apparent to a small percentage of the population who study the newly named organism, and it means little to the common observer. Such is the case with the Childrens Python (A.childreni).

At first glance, the name can have several meanings. This could be a small python, equating the word "Children's" to small like a child. This could be a python suited for children and one that is often owned as a pet by kids, as evidenced by the apostrophe "s." Or perhaps this is a large and dangerous python rumored to feed upon ill-mannered children of north-central Australia. Indeed, not many people associate the word "Children's" with the English chemist, mineralogist and zoologist J.G.Children, who was the keeper of the zoological collection of the British Museum from 1822 to 1840. Children's successor, John Gray, described the Children's python in 1842 based on a preserved, non-cataloged specimen in the museum's holdings.

Childrens Python: A Natural History

The Childrens python is a member of the genus Antaresia, which it shares the closely related spotted (A. maculosa), large blotched (A. stimsoni) and pygmy (A. perthensis) pythons. Members of this genus are characterized as being of small stature and thin-skinned with earthy coloration and a blotched or spotted pattern. Prior to 1985, all of these species were thought to be forms of the same species and not recognized as distinct. This renders pre-1985 data on childreni essentially useless because it isn't clear which species was actually being studied.

At least one of the preliminary assumption about the Childrens python can be viewed as accurate. It is certainly one of the world's smallest pythons. The adult Childrens pythons on our cage average about 30 inches in length, with one very large female growing to 38 inches. Females are generally larger than males in terms of both length and weight.

These are subtly attractive pythons. While they lack the loud, boisterous colors and patterns of many other species, Childrens python have a quiet beauty. They possess thin, silky skin that reflects a beautiful purplish iridescence in the right lighting. Their eyes are copper to gold with a well-defined pupil. The head is distinctly python in shape with pitted, labial scales around the mouth and the large plate-like scales adorning the top of the head. Adult coloration and pattern varies with the origins of the original bloodline founder animals. All Children python can be colored in earthy tones of brown, tan, rust, and terra cotta. Depending on locality, some retain significant amounts of blotching, and others become nearly patternless with age and maturity. Hatchlings are often boldly patterned with many fragmented blotches of a darker brown or bronze over a pale base color. As soon as they begin feeding and growing, this color pattern begins to fade and the contrast between the blotches and base color begins to decrease.

Children python can be s are found across the north-central portion of Australia, from about the 22nd parallel to the Timor Sea and among several offshore islands. They are found in a variety of habitats ranging from the dry interior to the humid coast, but they are most often found along water-ways within these areas. their preferred micro-habitat seems to be rocky hillsides, outcrops and cave systems, where they hunt other small reptiles and amphibians. Interestingly, The children python is often found in caves, adopting a semi-arboreal lifestyle along the crags and crevices for hunting the many species of small bats in the area.

Childrens Python In Captivity

Captive Children python can make great captives as pets or for study. They are undemanding and low maintenance. They are easily housed and fed because of their diminutive size. They generally have a calm disposition and are easily bred, making them terrific subjects for research too. Fort the last 15, years or so, an abundance of these fascinating small pythons have been available to herpetoculturists, which has also made them quite affordable for most budgets.

Housing childreni can be very basic. They don't require a lot of special treatment to do well. Our adults are housed simply in 32-quart tubs measuring approximately 23 inches long by 16 inches tall. These tubs are contained in a rack system that allows us to eliminate the need for lids. The racks have a section of heat tape at the back of each level providing an 88 to 90 degrees Fahrenheit hot spot on the back floor of the cage. For a substrate, we use shredded aspen bedding at a depth of about 2 inches. We provide a hidebox in the rear of the tub and a water bowl on the cooler end. (Excess humidity should be avoided; humidity needs are naturally met with this setup.) It's that easy. Children python thrive in this simple setup.

If you are more interested in naturalistic vivaria, Children python can be the perfect vivarium occupants. Pythons are often simply too large to be efficiently housed in a showcase-type setup. A pair of adult childreni will do great in a display cage of approximately 48 inches long by 18 inches deep by 24 inches tall. Let your imagination run wild with this setting up a naturalistic cage for this small python. They are at home in a variety of habitats, so sub-desert, woodland and rocky outcrop themes all apply. They will utilize rocky cliffs and large branches, so make sure to stabilize these to prevent them from falling and harming your snakes. Captive Children's are perfectly content to live on mice and small rats. Hatchlings should start on the smallest of pinky mice and quickly graduate through the sizes. Our adults are offered full-grown mice or a couple of rat pups each week. Adult childreni in our care have also readily accepted small chicks.

Making Children Python

The Children's python is one of the easiest pythons to breed in captivity. Feeding should be halted around November 1 to allow them to clean out their gastrointestinal tracts in preparation for their winter cycling. On November 15, we begin to lower the nightime cage temperature weekly, and reduce the ambient light levels and the number of hours the hot spots are on. By the end of November, nightime temps should be down to 68 to 72 degrees, with the daytime temps in the upper 70s. We provide a daytime hot spot of 86 to 88 for about six to eight hours, but it will probably not be utilized much, if at all.

Over Thanksgiving weekend, the pythons are paired up, and the breeding season officially begins. Copulations most often occur at night and are frequent. It is not uncommon to observe breeding activity almost every night for the next couple of months. Breeding activity seems to taper of during the coolest periods from around New Year's Day to February 1. Renewed interest occurs in mid-February as the temperatures begin to return to the usual summer levels.

Ovulation occurs around the lower third of the female's body, and is often witnessed in mid-March through mid-April. Relative to the snake's size, the ovulation swelling can seem huge. At this time, the animals are separated, and feeding soon resumes for the males.

After ovulation, the females soon begin a shed cycle. This shed will seem prolonged and typically lasts five to seven days longer than a normal shed. Once the shed completes, expect eggs in about 28 to 30 days.

The female should be given a secure nestbox in which to deposit her clutch. A small cat litter pan or large butter tub filled with moist sphagnum moss can be used successfully. The average clutch size for us is about a dozen eggs, but other breeders have reported as many as 20 in a clutch. We recommend moving the eggs to an incubator after they are laid to allow the female to regain lost weight for the next breeding season.

If the female is not scheduled to breed again the following year, we recommend trying maternal incubation. This is an intriguing part of python life that is frequently forgotten about in captivity. Female childreni make excellent mothers, and it is most rewarding to see them so what comes naturally. This also allows hobbyists to gain a lot of insight into the incubation process of pythons by taking temperature, humidity and observational notes. Trust me, your findings will lead to more questions, more hypotheses and more knowledge of what happens during python egg incubation.

If artificially incubated, the eggs should only be set up on slightly damp vermiculite. These small eggs have a tendency to absorb too much water and weep yolk if exposed to overly damp conditions. A good vermiculite-to-water ratio is 2-1 for these eggs. At an incubation temperature of 88 to 89 degrees, the eggs should hatch in about 55 days.

Childrens Python: Neonate Care

Hatchling Children's are very tiny snakes, and some extra precautions should be mentioned when setting up the hatchlings. First of all, their small girth should be noted when housing them in rack systems. They can easily squeeze through the tiniest gap, and this makes keeping them in a lidless rack system difficult.

We found what works best is tp house them individually in 6 1/4 inch-diameter deli cups. The cups can be punched around the rim with tiny ventilation holes for air exchange. They can be the placed on a thermostat-controlled strip of 3-inch heat tape to provide a hot spot. Make sure only a third or so of the cup is directly on the tape to prevent overheating. A 2-ounce soufflé cup makes a great water bowl, and a folded piece of newspaper on top the aspen creates a sufficient hide.

Feeding new hatchlings can also be tough because of their small size. We generally offer food about three weeks once they shed and fully digest their yolk. No more than a day-old pinky mouse can be offered. Fortunately, this size is easy to come by if you breed your own mice, and most frozen rodent distributors will fill orders for one-day-old pinkies.

Most of our hatchlings have started feeding on live newborn mice, but a few need some assistance. There is a percentage of each clutch that holds out for foods that smell more like their natural prey, and lizard scenting becomes necessary. Anoles work well for this, as does the shed skin of skinks and geckos. Sometimes one or two babies in a clutch will be extra rebellious and require a few assist feedings. We use pieces of mouse tail for this. Just break the tail off of a frozen rodent, let it thaw and cut it into 1-inch sections. Insert the piece into the snake's mouth, and most often the baby will do the rest. This is not very nutritious, but it provides a good calcium boost and has saved many baby snakes for us over the years.

Final Thoughts on Childrens Python

The Children python is a great small species to keep. These pythons are undemanding in care and easy to breed. These factors make them terrific study subjects as well as pets. They also offer great change of pace for breeders working with larger snakes and provide a back-to-basics project for even the most seasoned herpers.

We believe that true herpetoculturists can find interest and fascination with any reptile, whether they are "money makers" or not. While Childrens python is considered investment animals, they are great, easy-to-care-for snakes that deserve recognition.

Red-bellied Black Snake

Pseudechis-porphyriacus-range.jpg

Pseudechis porphyriacus or Red-bellied Black Snake

The Red-bellied Black Snake is a diurnal (day time) predator. The average length for this snake is 1.5 metres, but they can reach a length of 2.7 metres. They enjoy living around watercourses and marshy grounds, as their favourite foods (frogs, eels and lizards) are usually found in these areas. The introduction of the Cane Toad almost wiped this species out. Fortunately there seemed to be a number of Red-bellied Black Snakes that chose not to eat toads. These animals seem to have passed this trait on to their offspring, resulting in Red-bellied Black Snake population numbers becoming more secure.

The Red-bellied Black Snake is a shy and docile snake. Red Bellies have been known to strike with their mouths closed to scare off unwanted attackers, which is contrary to their reputation as ferocious animals. The venom of the Red-bellied Black Snake is quite low in potency compared with most other venomous species. Its venom possesses procoagulant (blood-clotting) and myolytic (muscle-destroying) activity. It is not unusual for necrosis (tissue death) to occur at the bite site.

The Red Bellied Black Snake bears live babies, with litters of up to 20 not uncommon.

Tiger Snake Envenomation

First Aid for tiger snake envenomation is pressure-immobilization

The snakes in the group defined here are grouped together because of similarity in clinical aspects of the envenomations they may cause. Several genera are represented, and among the species included are:

  • Mainland Tiger Snake
  • Black Tiger Snake
  • Rough-Scaled Snake
  • Copperheads
  • Pale-Headed Snake
  • Broad-Headed Snake
  • Stephen's Banded Snake
  • Small-Eyed Snake

Signs and Symptoms

Tiger snake venom has a wide range of effects on humans. It contains pre-synaptic and post-synaptic neurotoxins, myotoxins and procoagulants. Significant envenomation by any species of this group may result in:

  1. Neurological impairment
  2. Paralysis
  3. Incoaguable blood
  4. Rhabdomyolysis
  5. Renal failure secondary to myolysis

Treatment

First aid for tiger snake envenomation consists of a pressure bandage and immobilisation. In cases where a pressure bandage has been applied correctly, it can be left in situ indefinitely while the patient is feeling no discomfort as a result. If it becomes appropriate to remove a pressure bandage, it is necessary to have antivenom and haemostatic support ready. In severe cases, a patient may require ventilatory support.

Antivenom is indicated for any clinical manifestations of neurotoxicity, myolysis or severe coagulopathy.

Antivenom

Tiger snake antivenom can be used effectively for envenomation by any of the species listed above.

Tiger snake antivenom supplied by CSL Ltd is equine in origin.

Spotted Black Snake

Pseudechis-guttatus-range.jpg

Pseudechis guttatus or Spotted Black Snake

When is a black snake NOT black? Colour variation among most species of black snake is extreme. The Spotted Black Snake can range from cream to orange to black, with speckling or without. As with other members of the Black Snake family, the Spotted Black Snake is not an aggressive animal. When provoked, they will often flatten their heads to appear larger and more threatening.

The Spotted Black Snake grows to an average length of 1.2 metres. Their diet consists of lizards, frogs, small mammals, and other snakes. They are an egg laying snake, with the female producing approximately 13 eggs in a clutch.

The venom of the Spotted Black Snake contains a coagulant, an anticoagulant, haemolysin, a haemorrhagin, and a neurotoxin. The preferred antivenom is specific Black Snake. If this is unavailable, Tiger Snake antivenom will give adequate cross protection.

Reptile Parasites

Pesky Reptile Parasites

Parasites are animals that live on or in another animal (the Host). Although it is not their intention to kill the host, they do however usually have a deleterious effect. A parasite infestation can either be external or internal.

External Reptile Parasites

Reptile Parasites: Ticks

It would be extremely unusual for captive bred animals to have ticks. However if someone was to keep their animals outdoors or using natural substrates it is possible to introduce ticks to your reptiles.

Ticks are blood feeders and on snakes take up their feeding position in the soft skin between the scales. The problem with ticks is that they irritate the reptile and a heavy infestation could cause anemia. Ticks can also carry other parasites and viruses that can be transferred via the blood feed.

Reptile Parasites: Mites

The snake mite is also a blood feeder, a popular among reptile parasites. An indicator that your snake might have mites if it spends a lot of time soaking in its water bowl. Check in the water bowl for the mites that have drowned. These will be visible on the snake particularly around the eye socket, in the crease under the chin and under scales (look for scales that appear raised). If there is a heavy infestation the snake will also have number of white speckles in its body. This is in fact mite faeces.

Reptile Parasites: Treatments

There are a variety of treatments available. The one I prefer is  an aerosol sold by Callington Haven called Top of Descent spray (D-Phenothrin). This is convenient as you can simply remove the water bowl and spray a fine mist in the cage for a few seconds (leaving the snake in the cage). After 10 minutes, open the door and ventilate. The spray seems to degrade after about 12 hours, so it will be necessary to repeat the treatment in 5 days to treat any eggs that may have hatched.

Other products available include Orange Medic & Sheltox Pest Strips.

NB: Be wary that all these treatments can harm your reptiles if used incorrectly.

Reptile Parasites: Internal Parasites

You should be aware that wild caught rodents, fruit vegetables, crickets, moths, cockroaches, snails, and even laboratory bred rodents can carry intestinal parasites.

Rodents for snake food are always safest if frozen for a few weeks and then thawed prior to feeding off. This freezing will kill a number of internal reptile parasites.

Reptile Parasites: Best Counter

Probably the best practice here is to get faecal samples checked by your vet. Initially on recept of the animal and then every 6 months. If treatment is required the vet will recommend a product and reptile parasites will be avoided.

Brown Snake Envenomation

Brown-Snake-treatment.jpg

First Aid for brown snake envenomation is pressure-immobilisation

Brown snake is widespread outside urban areas, and particularly common around buildings in rural environments. The group is the most important in terms of fatalities, being responsible for more deaths in the last twenty-five years than any other group. The fact that brown snakes are very fast-moving also adds degree to the danger they present. While all snakes are generally variable in appearance, brown snakes are remarkably so, leading to possible problems with identification.

Among the toxins contained in their venom is a very potent presynaptic neurotoxin, one of the strongest of toxins found in snakes. The venom also contains a postsynaptic neurotoxin and a procoagulant. Unlike the venom of most dangerous Australian elapids, that of brown snakes has littles or no myolytic activity.

Signs and Symptoms

Early collapse, a few minutes after the bite, is not infrequent in cases of brown snake envenomation, possibly due to haemostatic disturbance resulting from coagulopathy. Bloods will typically indicate prolonged clotting times. Thrombocytopenia is also evident from haematology. One diagnostically distinct feature of brown snake enevenomation is the absence of rhabdomyolysis, which in cases involving other species manifests as myoglobinuria. Coagulopathic effects can also result in disseminated intravascular coagulopathy, putting the patient at risk of cerebrovascular accident.

Treatment

First aid for brown snake envenomation consists of a pressure bandage and immobilisation. In cases where a pressure bandage has been applied correctly, it can be left in situ indefinitely while the patient is feeling no discomfort as a result. If it becomes appropriate to remove a pressure bandage, it is necessary to have antivenom and haemostatic support ready. In severe cases, a patient may require ventilatory support.

Brown Snake Antivenom

It is generally accepted that the initial treatment for syptomatic brown snake envenomation involves administration of two ampoules of monovalent Brown Snake Antivenom. Brown snake antivenom supplied by CSL Ltd is equine in origin.

Collett's Snake

Pseudechis-colletti-range.jpg

Pseudechis colletti or Colletts Snake

An inhabitant of the Black Soil Plains of central western Queensland, Colletts Black Snake is considered one of Australia's most beautiful snakes. The colour of individuals ranges from brown to cream to red, with dark bands or spots. The environment in which this snake lives is harsh and arid, where during the summer months the ground temperature often exceeds 45 degrees Celcius. The only way to escape from the extreme heat is to go deep underground. The snakes achieve this by utilising the deep cracks that appear in the ground. The Colletts Snake can reach a maximum length of 2.5 metres. Mature animals often become very thick in the body and as a consequence are heavy and strong.

As with all members of the Black Snake family, the Colletts Snake is not inclined to bite. Their venom has a number of low molecular weight toxins and two separate myolytic proteins. It has the potential to produce myoglobinuria. There is also high phospholipase activity. Colletts Snake feed on rodents, other reptiles, birds, and frogs.

On rainy nights when the burrowing frogs come up from underground, these snakes will come out to feast. This is a rarely-seen animal in the wild and there are possibly more of these animals in captivity than now live on the Plains. Females are egg layers, producing approximately 8 to 20 eggs in a clutch.

Traveling Snake Seeks Suburban Home

"You can take the snake out of the backyard, but you can't take the backyard out of the snake."

Some snakes appear to have a distinct preference for living in suburbia - and are skilled at disguising their presence among us.

Research by a La Trobe University zoology student has revealed these unexpected findings, and other unusual facts about Melbourne's Tiger Snakes.

Tracking translocated Tiger Snakes implanted with transmitters, Bachelor of Science (Conservation Biology and Ecology) Honours student, Heath Butler found that some prefer suburban to rural life.

Four of eight snakes tracked after translocation from suburban backyards to a regional park between August last year and March this year headed straight out of the park into other suburban backyards about a kilometre away.

And when taken from their new backyard home back to the park, they again turned up in the same backyard.

All snakes are protected in Victoria. Under Department of Sustainability and Environment policy, snakes captured in 'inappropriate' locations are translocated to a suitable habitat within five kilometres of their capture point, or euthanased.

"It seems that snakes were so used to the good life in suburbia - with readily-available water and food - that they headed straight back into a similar environment when relocated into the unfamiliar landscape of parkland," Mr. Butler said.

There was another surprising result. By monitoring the snakes' daily habits, Mr Butler believes he may have debunked the old idea that snakes are active only in very hot weather. "The Eastern Tiger Snakes (Notechis scutatus) I worked with appear more likely to be active on relatively cool, sunny days. They disappear, at least between 12 noon and 2 pm, on days when temperature exceeds 30 degrees Celsius," he says.

Curious about snakes since his adolescent years at Port Fairy, Mr. Butler conducted his research, sponsored by three interested parties - Parks Victoria, Australian Geographic and the Melbourne Zoo.

He worked initially with several of the 45 Victorians licensed to catch snakes in 'inappropriate' - read urban and suburban - areas and to release them on public land.

Melbourne Zoo veterinarians surgically inserted tiny transmitters into eight snakes captured in suburban backyards within five kilometres of Westerfolds Park, Templestowe.

These snakes were then released in the park. Six snakes resident in the park were also implanted with transmitters then released at their site of capture. Mr. Butler then electronically monitored their movements and other activities.

"Translocation had such significant effects on the behaviour of the snakes that the relevant authorities may wish to re-examine its success as a strategy to reduce human-snake conflict," he said.

"The two groups of snakes - residents of the park and those translocated - behave differently. Although the health of translocated snakes remained similar to the local snakes, they exhibited home ranges about six times that of the locals and half the translocated snakes headed off to suburban backyards within a kilometre or so of the park.

"It seems that they are quite happy in suburbia, probably because of well-watered gardens and sufficient food, possibly frogs. Most people were unaware of a snake in their backyard until I informed them."

Over the eight months he captured snakes on 70 occasions, noting their location and monitoring their condition. His catching method was simple. Locate the snake with his tracking equipment, seize it by tail - with bare hands as gloves are too cumbersome - and drop it into a bag.

Mr. Butler was bitten only once, on the hand, but recovered fully after an anti-venom injection. He says his research findings may have been influenced by the drought, which could have made well-watered suburban backyards unusually attractive as snake habitats.

But the season would have had little effect on some other findings, such as the bigger the snake, the better it was at concealment. 1.2 metres long are some of the snake he handled.

Tiliqua multifasciata or the Centralian Blue-tongued Skink

Did you know...

  • The red colouration of the centralian blue-tongued skink helps it blend into the arid environment in which it lives.
  • During the warmer seasons, these blue-tongued skink can be active at night.
  • Between two and seven young blue-tongued skink are born in the summer months.
  • The sizes of the new born young blue-tongued skink from one litter can vary greatly, with the largest being as much as five times the size of the smallest.
