Black Spiny Tail Iguana

Our little spiny tail hasn't been named yet. He was caught in Wilmington running loose by a doctors office. He is very fast and scared of humans but we're working on changing that. He will eventually be used for education to show the differences between types of iguanas.

About the Black Spiny Tail Iguana

The black spiny-tailed iguanas, are a native species of Mexico and Central America. They are typically found in hot, dry areas but can also be found in forested, moist areas in Belize. These are the fastest running lizards in the world with a recorded speed of up to 21 mph.


These iguanas are omnivorous and can be found feasting on anything from green leaves and shoots to tasty insects, eggs and small animals. Juveniles though, tend to be more insectivorous than the adults.


The female normally lays its eggs in the sand 8 to 10 weeks after mating and the eggs sit there for about 90 days prior to hatching. 


The black spiny-tailed iguanas are extremely aggressive reptiles and will bite when they feel threatened. They are of least concern on the IUCN species list but are still subjected to habitat loss and increased hunting (as well as the eggs) as they are considered a delicacy throughout Central America.
