Most of them can’t. Just as there are several types of alligators whi live in different areas/environments, there are two types of iguana(that i know of) that exist: the common iguana and the marine iguana.
Iguanas are kept as pets, but are dangerous if angered/mistreated, so if you have a pet iguana or are planning to keep one as a pet, treat it well. :)
