More about rhinoceros iguanas...

The rhinoceros iguana is also known as the horned ground iguana. These common names are a reference to the enlarged, horn-like scales found on the snout of the animal.

Rhinoceros iguanas are active by day (diurnal) and like many reptiles spend the day in a mixture of basking in the sun to warm their bodies, feeding and then retreating to the shade when they become too hot. This is the only kind of temperature control afforded to ectothermic (cold-blooded) animals. They spend the night in caves, hollow trees, rock crevices and burrows.

Rhinoceros iguanas are primarily herbivores feeding on leaves, shoots, fruits, flowers and seeds. However, land crabs, insects and carrion are also eaten.

Breeding takes place at the start of the rainy season in April to May. Females lay a clutch of up to 32 eggs, about 40 days after mating. The eggs are laid in a nest dug in sand and which is guarded by the female for the first few days after laying. The incubation period for the eggs is around 85 days.
