Green iguanas and water
UF/IFAS notes that green iguanas are almost always found near permanent water in many habitats and are strong swimmers. When startled, they may dive from land or trees into water.
The tail as a swimming tool
The long muscular tail provides much of the propulsion, while the limbs can be held closer to the body.

Marine iguanas
Marine iguanas represent a specialized endpoint: they use the marine environment for feeding and must then return to land to warm themselves.
Can they breathe underwater?
Swimming should not be confused with underwater breathing. Iguanas are air-breathing reptiles and must surface to breathe.
