The incisors at the front of the mouth have a sharp biting surface and are used for cutting or shearing food into small chewable pieces. There are eight incisors in both primary (baby) and permanent sets of teeth (dentitions).

Birds do not have teeth and therefore do not chew food like mammals do. They grind up their food in an organ called a gizzard. This is a muscular organ that is part of the stomach.

8). Warm blooded animals

Mammals and birds are warm-blooded, which means that they can make their own body heat even when it is cold outside. Whether it is sunny and hot outside or there is a snowstorm and it is very cold, warm-blooded animals have body temperatures that usually stay the same.
