Why do lizards lay on rocks?

Answer 1

As cold-blooded animals, lizards cannot produce their own body heat, so they need to obtain it from their environment. Rocks hold in heat much better than air, so lizards often lie on them to warm themselves.

Answer 2

Sea otters use rocks as tools to break open prey with exoskeletons or hard shells. Floating on their backs, their bellies act as table-like surfaces on which to use the rocks.

Answer 3

Sea lions roll around in and coat themselves in the sand to protect themselves from the sun.

Answer 4

Lizards need heat to survive as they are cold blooded. Rocks trap the heat from the sun and hold that heat long into the cool nights so the lizards sit on/under them to stay warm

Answer 5

Basking in the sunshine.
