Fish


Fish are animals that live in water. Fish have fins that help them to swim. Most fish have slimy skins covered with scales which are very small and can hardly be seen.

Fish breathe through gills. These look like a comb and lie on each side of the head. Fish take in water all the time. The water flows in through the mouth, over the gills, and out through the sides of the head. When a fish takes in water, it is not drinking but breathing, and the gills absorb oxygen from the water.

The body of a fish is made up of the head, the trunk, and the tail fins. There are many different kinds of fish which have many different shapes an colors. Some fish are long and thin, while others are flat and rounded. Most fish have bodies which are broad at the trunk region and narrow towards the head and tail.
