What is it?

The Andros rock iguana is a large lizard that lives only in the Bahamas, mostly on the island of Andros and a few nearby cays. It can grow up to one and a half metres long — about the height of a tall nine-year-old — and it is one of the most impressive reptiles in the Caribbean. Though it looks tough, it is actually a gentle plant-eater.

Rock iguanas love to sunbathe on limestone rocks and warm sandy ground in the morning sun. Like all reptiles, they are cold-blooded, which means they cannot generate their own body heat and rely on the sun to warm them up before they can move quickly. On a sunny morning you might spot several iguanas stretched out like little sunbathers in a row.

The Andros rock iguana eats leaves, flowers, and fruit. It plays an important role in the ecosystem by spreading seeds — when it eats fruit and wanders around, it deposits seeds in new places through its droppings, helping plants grow across the island. Many plants on Andros depend on iguanas to spread them around.

Baby iguanas hatch from eggs buried in the warm sand. They emerge looking like miniature versions of adults and must immediately find food and shelter on their own. The sandy cays are perfect for nesting because the sun warms the eggs naturally, doing the work of an incubator.

The Andros rock iguana is listed as a vulnerable species, which means scientists are keeping a careful eye on it to make sure its numbers stay healthy. National parks on Andros protect important iguana habitat, ensuring these magnificent lizards have safe places to live, sunbathe, and lay their eggs.

Discussion prompts

  1. 01Iguanas are cold-blooded and use the sun for warmth. How is this different from how your own body stays warm?
  2. 02The iguana spreads seeds through its droppings. Can you think of other animals that help plants move to new places?
  3. 03Why might it matter that an animal is found only in one country?
  4. 04If you were designing a national park to protect iguanas, what three things would you make sure to include?

Classroom activity

Draw a 'day in the life' comic strip of an Andros rock iguana — at least six panels showing morning sunbathing, finding food, resting, and any encounters with other animals. Add speech bubbles or thought bubbles to give your iguana a personality.
