Blue spiny lizard

Sceloporus serrifer cyanogenys

Blue spiny lizard

Blue spiny lizards are closely related to iguanas. They get the name from their scales which are large, pointy and ridged. They use these spiny scales for defence. Blue spiny lizards are blue on their shoulders but males are also blue on their back, chin, throat and stomach and they show off their throats and underbellies to win a mate.

Blue spiny lizards are active during the day. When they are not hunting for food they spend their time hiding from predators and sheltering from the heat.

Our blue spiny lizard can be found in the reptile house. It shares its home with our pancake tortoises.
