Turtles 

They sunbathe to warm up during the day. They must sunbathe before diving for algae because the water can drop their body temperature. At night, they pile up to keep warm.

Marine Iguana 

Crocodiles resemble alligators. Males are 15 feet tall. Alligators enjoy 82-92 F when active. Warming up, they sunbathe. Wintertime, they burrow in dirt or stay underwater.
