There is little information available on the behaviour, reproduction and social systems of the five-keeled spiny-tailed iguana. However, many aspects of its life history can be assumed to be similar to other iguana species. Like all other iguanas, the five-keeled spiny-tailed iguana is active during the day (5).
Similar to other members of the Ctenosaura genus, the five-keeled spiny-tailed iguana is oviviparous. Little is known about the number of eggs laid in the wild, although a captive bred female is known to have laid five eggs in one clutch (2).
Unlike the adults, the young five-keeled spiny-tailed iguana relies heavily on animal protein, mainly from insects, and become increasingly herbivorous as they mature. Adults are mostly herbivorous, but small mammals, birds, other lizards and eggs make up a small part of their diet (3).
