What is a Fish?
Fish is a vertebrate organism that lives in water and breathes through its gills.
Which different body structures of a fish help in locomotion?
There are three main structures that aid in locomotion: streamlined body, fins, and tail.
Streamlined body
Fish have a streamlined body. It means that the body has Bulged in the centre, but Tapering at both the ends. This type of body offers little or no resistance to the flow of water allowing easy movement in the water.
Fins
Fins are the small limb-like structure on the body of the fish that enables it to move. Fins that are present laterally (on the sides) are called Pectoral Fins.
Tail
The tail helps in the locomotion of fish by displacing the water allowing fish to move forward. The fins that are attached to the Tail of the fish are called Caudal Fins.
