Parts of a fish and their functions

The eyes of a fish are always open; they have no eyelids.

The mouth is used to catch food. Only some fish have teeth.

The body of the fish is protected by a thin but hard coat of overlapping scales and a coating of slime!

The lateral line is a line of very small pores (holes) that sense water movements and vibrations.

The gills Fish use their gills to breathe. They suck in water through their mouth and breathe out through the gills.

The tail is known as the caudal fin. It swings from side to move forwards, left and right in the water.

The tail Fish with a continuous caudal fin are good at swimming in and around cracks and crevices.

The tail Fish with lunate (moon-shaped) tail tend to be the fastest swimmers and can swim for a long time.

The tail Fish with forked tails swim constantly without stopping (even when they are asleep!)

The tail Fish with truncated or rounded tails are usually strong, but slow, swimmers.

The fins Fins are used for swimming and sometimes for protection. They are made of skin with tiny bones or cartilage in. Fins come in lots of shapes and sizes.

The dorsal fin is a spiny, hard fin that helps to keep the fish upright.

The pectoral fins help the fish move from side-to-side. They are also known as arm fins.

The pelvic fin This is also called the leg fin. It helps the fish to move up, down and turn.

The back fins The fins at the back of the body stop the fish from wobbling in the water.
