In the Wild:
This iguana is defined by its three projecting horns. Rhino iguanas are diurnal lizards, which spend much of the day basking on exposed rocks. The males defend territories that are most attractive to females in terms of basking and sheltered positions. Females lay between 2-34 eggs, the average being 17.
Destruction fo the habitat, illegal pet trade and being hunted for their meat all put the iguana at risk. Also predated upon by invasive species of predators.
