Western swamp turtle  (Pseudemydura umbrina)

Aestivation: Period of dormancy occurring in hot, dry periods, analogous to hibernation in winter.
Carapace: The top shell of a turtle. In arthropods (insects, crabs etc), the fused head and thorax (the part of the body located near the head) also known as ‘cephalothorax'.
Endemic: A species or taxonomic group that is only found in one particular country or geographic area.
Larvae: Stage in an animal's lifecycle after it hatches from the egg. Larvae are typically very different in appearance to adults; they are able to feed and move around but usually are unable to reproduce.
