A lizard has a thick and scaly skin that retains the moisture. A little water can last a long time. When there is excess heat, the lizards lie in the shade or under the sand to escape the sunrays. The only birds that live in the sea are penguins. Instead of wings, they have flippers, which help them to swim.
Penguins come to surface of the water to breathe, and move on to the land to lay their eggs.
