Sun lovers, these lizards spend much of their time basking in the sun. Dominant males prove their worth to females by defending the best basking spots and safest burrows. Males will fight viciously for their territory making it hard for Zoos to keep more than one male in an exhibit.
Rhinoceros Iguana numbers are decreasing in the wild due to habitat destruction and being hunted for food. Taronga Zoo is one of the few Zoos to have successful and regular hatchings of Rhinoceros Iguanas. Up to 20 eggs are laid in short burrows which are collected by staff and hatched in incubators to ensure their survival.
