Pyxis arachnoides brygooi
The spider tortoise is one of the smallest land tortoises with a shell length that reaches 6 inches. Its name comes from the yellow markings on its shell that resembles spider webs. Males are slightly smaller than females and have a longer thicker tail. This is a critically endangered species due to habitat loss. Spider tortoises spend time under vegetation to regulate their body temperature. They are most active during November to April when vegetation is plentiful.
