There are 35 different iguana species

You might be familiar with the green iguana (Iguana iguana), which is by far the most common and widespread iguana species in the Americas. However, iguanas come in many shapes, colors and sizes.

One of the most visually striking members of the Iguanidae family is the Grand Cayman iguana (pictured). Also known as the blue iguana, this exquisite creature is one of the few naturally blue-hued animals in the world. It's also the heaviest of all iguanas.

While it once existed in great abundance on the island of Grand Cayman, the species numbers have been on a steady decline for the past couple centuries due to habitat loss and predation by domestic dogs and cats. They are currently listed as endangered on the IUCN Red List, and there are only a handful of individuals left in the wild.
