Special Sub-Topic: Frogs and Reptile Mania
|A frog has a backbone.|
True. Frogs have a backbone that is rather soft. This backbone has to be soft to handle the frog's constant jumping around that could fracture a hard backbone.
A frogs backbone contains only 9 vertebrae compared to a humans 24 vertebrae.
The function of a frogs skeleton is locomation and maintaining its posture.
The only real differences with a frogs skeleton and a humans is that one of the functions of a frogs skeleton is not to protect its ribs as frogs fo not have any.
Also a frogs skeletal system is only made up of 159 bones compared to a humans 206.
|How many fingers do most frogs have?|
4. A frog has 4 fingers on its webbed "hands". These "hands" need to be webbed to help the frog to swim away quickly from predators and also allow extra grip on slippery surfaces such as lily pads and slippery trees.
The fingers of a frog are sticky to aid the frog to climb slippery trees more safely.
|How many toes does a frog usually have?|
5. These toes are webbed to allow for a quick escape from predators. These also toes make it easier to jump and climb up trees.
Frogs also use their feet for digging to burrow into sand to help stay moist in hot conditions. Some frogs amazingly enough have so much webbing on their feet that they are able to jump and use their feet to slow them down.
|When does a lizard bask?|
When it is cold.. A basking lizard warms its body using heat from the sun. Lizards often are seen basking in the sun in the cooler months of the year.
Lizards range in size from just a few centimetres to almost 3 metres (Komodo dragons).
Many species of lizards are able to regenerate lost limbs or tails.
Lizards feed on a wide variety of things ranging from nuts, berries, vegetation, insects to even medium sized mammals.
Only a a few lizards have been proven to be venomous such as the "Gila Monster" and the "Mexican bearded lizard".
|How does a gecko clean its eyes?|
With its tongue. A gecko's eyes dry out quite quickly since they don't have any eyelids, so it uses its tongue to clean them and keep them moist. A gecko's tongue is quite clean and is a more reliable way to clean its eyes than any other way.
Geckos are small to average sized lizards that are typically found in warm climate all over the world.
As a defence mechanism many species of gecko's spray a foul smelling material such as faeces at their predator.
|What is the largest Australian dragon lizard?|
The frilled lizard. The frilled lizard (also called the "frilled neck lizard") is substantially larger compared to the other Australian dragon lizards. This lizard is often found in gardens in central Australia. When frightened the frilled lizard opens its mouth and extends its frills in order to scare a potential predator away.
Adult frilled lizards have been known to grow up to 1 metre in lenghth.
This type of lizard is commonly found in the Kimberly region of Western Australia and along most of the top of Australia as well as southern New Guinea.
The main prey that the frilled lizard eats includes small to medium sized arthropods as well as termites, ants, spiders and many other small insects.
The only real predator of the frilled lizard is the Morelia which is a type of non-venomous python that is found in the frilled lizards habitat.
|What is the sole food of the Thorny Devil?|
Ants. The Thorny Devil is a small prickly lizard that is found only in central Australia. This lizard has been known to consume up to 5000 ants in a sitting.
The Thorny devil grows to around to 20cm in length as is coloured in different shades of brown which are usually very similar to its habitat.
Mating season is September-December and a clutch of usually 3-10 eggs is laid during this time in a burrow underground.
|A snake can't blink.|
True. A snake's eyes are covered with transparent scales which are shed with the skin at intervals. A snake can't blink because it has no eyelids.
There are thousands of species of snakes ranging from snakes that live in the water like "Coral snakes" to snakes that live in deserts like the venomous brown snakes that live in Australia.
|All snakes lay eggs.|
False. Some snakes actually give birth to live young like the Rattle snake for example. However, most snakes do lay eggs that are very soft and leathery.
A snakes eggs are usually soft and leathery. Most egg laying snakes do not look after their young so snakes usually learn to become dependant quite fast.
|About how many species of Australia's front-fanged snakes are potentially dangerous to humans?|
About 20. Some of the ones that are potentially dangerous in Australia are the Brown snake and some species of taipan. On average, a few hundred people in Australia require anti-venom each year.
