This is the time of the
many egg-laying reptiles lay their eggs.
This water dragon has dug a hole about
70mm deep and deposited nine eggs in
The eggs are about 20mm
have a soft leathery casing. Here she is
giving them a gentle push with her nose to make sure that they are firmly in place.
|The next job is to cover them with soil and grass for protection and to prevent them from drying out.||When finished it can be difficult to tell where the nest is. The eggs are left to hatch and the female takes no further interest in them. At the Reptile Park the eggs are collected and placed in an incubator where they hatch 60 to 70 days later.|
is much more casual where it deposits its eggs. As is typical with geckos it lays two eggs, which in some species of geckos such as these are hard shelled, and on occasions can be stuck together as the ones in the photo. The eggs are usually left in a hollow or else stuck to a suitable surface and left to hatch, there is no attempt by the female to cover or hide them. .
Leopard Geckos bury their eggs under a stone which gives them protection as well as helping maintain the humidity to a suitable level. The eggs do not have hard shells like the Day Geckos nor are they stuck together. They are encased in soft leathery skin which is kept tight by internal pressure and they expand slightly during incubation.
|As the days become warmer lizards shed their skin, when adult usually once for the year but it could be several times in young growing animals. New Zealand geckos like the green gecko pictured remove theirs complete not unlike a person taking off a wetsuit. Even the feet and the clear disc over the eye are included. Most other lizards shed theirs piecemeal and in some cases will pull portions off and eat them.||
The colour of the male
Iguana changes from green to an attractive orange to impress the female.
This along with much head bobbing and the spreading of his dewlap like
a flag is a prelude to mating when the female is ready. There can be
a certain amount of biting from both parties when this occurs.
