Class reptilia
Usually, reptiles posses skin covered with very fine scales. The reptiles are ectotherms, which means that their body temperature changes (unlike mammals and birds). These animals use lungs to breathe even if they live under the water. If a reptile is lying in the sun, it will have warm blood, and in the night, they will have cold blood.
Examples of these animals are: Snakes Lizards Chameleon Gecko |
