The fin on a fish's back is called the dorsal fin. Its main purpose is to stabilize the animal against rolling and assist in sudden turns. Some animals have developed dorsal fins with protective functions, such as spines or venom.

∙ 14y agoThe caudal (tail) fin is the driving force used to propel the fish forward. The paired fins are mainly used for brakes and steering and the dorsal and adipose fins are used as keels on a yacht/boat in most fish. There are variations on this. Sea horses are one example where the dosral fin is used for propulsion but there are many other variations.

Flamessurgeon:
The paired pectoral fins are located near the gill cover and are used for maneuvering the fish. These fins have been adapted, in the case of some bottom-dwelling species, so fish can prop themselves up or even walk around above or below water. Sometimes the pectoral fins are equipped with spines for defense.
