Crocodile on a Sunny Bank
A crocodile does not make enough body heat on its own, so it uses the sun and water to stay warm or cool. It lies in the sun, opens its mouth, and slips into water when it needs a different temperature.

In the picture
- Badge 1: the crocodile’s back on the sunlit bank, where it soaks up warmth.
- Badge 2: the crocodile’s wide-open mouth, which lets heat leave or enter.
- Badge 3: the water around the crocodile’s tail, where it cools down.
Examples
- A lizard resting on a warm rock.
- A cat moving from a sunny window to a cool floor.
Key takeaways
- Crocodiles get most of their body heat from outside their bodies.
- Basking, gaping, and entering water help a crocodile keep a usable body temperature.
