are monitor lizards. They are presumed from the iguana type.
There are about 20 species of goanna world wide, 15 of which are
found in Australia. They can be carnivorous as well
as vegetarian. They are dark in coloration varying from green,
yellow, grey or even just black. They are known for being
predatory lizards therefore are large in size and quite bulky
with sharp teeth and claws. There is one difference which other
lizards can call as an advantage; when a tail is cut of a claw
is damaged they don’t grow again. They lay their egg in burrows
or in nests under the ground. Another safe place they usually
lay their eggs is in termite mounds. This is a very good hidden
place which is secure in case of other animals that look for
eggs; they are very well hidden. Another advantage is that when
the eggs hatch the little baby goanna get food, the termites
being their source of food for a while.
