Pectoral Fin




A Pectoral Fin is one of the two paired fins positioned towards the front of a fish's body, often just behind the head.

Pectoral fins are usually highly mobile and are normally used for manoeuvring.

One peculiar function of pectoral fins is the creation of the dynamic lifting force that assist some fish, such as sharks, in maintaining depth and also enables flying fish to "fly".
