An iguana is a big lizard with distinctive spines running down its back. If you keep an iguana as a pet, you'll want to feed it a lot of fresh vegetables.

Iguanas look a little intimidating, since they grow as large as six feet long to the tip of the tail and have a head that resembles a dinosaur. While pet iguanas can sometimes be somewhat aggressive, they can be tamed with enough handling. The word iguana is Spanish, and it comes from a West Indies language, Arawak, and its word for this particular kind of lizard, iwana.
