The Iguanids

In 1989, Darrel R. Frost and Richard Etheridge re-classified the eight subfamilies which constituted the family Iguanidae into eight separate families. The resulting families, as outlined below, make up what are still known as "iguanian lizards" or "iguanids". (The eight genera which now make up the family Iguanidae are now known as "true iguanas" or "iguanines".)

Many iguanids are very popular in herpetoculture, and here I have tried to give a summary of the natural history and best captive care practices for each popular species.
