Did You Know?!

  • Rhino iguanas get their name because of horn-like structures that are found on the heads of males. It is not known if these structures serve any purpose, but may aid in courtship.
  • Male iguanas go through elaborate courtship behaviors of head bobbing and erecting the spines along the back. Normally, iguanas are quite timid and will flee if approached, but during courtship the males can be quite aggressive.
  • Rhino iguanas are much more terrestrial than the green iguanas which allows them to live in rockier and drier areas. They are rarely found in trees or even forested areas.
