1. There are around 35 species of iguana
And they’re all a bit different – although the family has undergone some reclassification in recent years.
The iguana that most people are probably most familiar with is the common Green iguana, which is also a popular pet. Some others include the Marine iguana and the Lesser Antillean iguana (both of which we’ll learn more about later), the Desert iguana which doesn’t even really look like an iguana, and the Spiny Tailed iguana which can be smaller than a meter in length.
