There is generally a prominent dorsal fin on the back of the dolphin though it is absent in northern and southern rightwhale dolphins. Some of the river dolphins do not have a dorsal fin, but only a slight ridge or hump on the back. The size, shape and position of the dorsal fin varies from one species to another. The fin is not supported by any bone, but by tough fibrous tissue inside it. Dolphins can have fins that are falcate, triangular, bluntly rounded or totally absent. The functional significance of these different styles of in is uncertain. Some people believe that dorsal fins help dolphins to maintain stability in the water while others believe that a well-developed fin is not essential for survival. However, the blood vessels in the dorsal fin do help to control body temperature. It acts as a heat exchanger during intense activity or when swimming in particularly warm water.
The caudal fin of a fish, also known as the tail fin, is primarily responsible for propulsion and steering. It generates forward movement by pushing water backwards when the fish moves its tail side to side. The shape and size of the caudal fin can affect the speed and agility of a fish.
Another name for a tail fin is a caudal fin. It is the fin located at the end of a fish's body, which helps with stability and propulsion.
The caudal fin is the tail fin. Although there are four types, fish only have one caudal fin.
what do the dorsal and anal fins do for a fish
I think that the largest fin of a perch is the first dorsal fin, the one that is located on the top of the fish and is spiny.
The caudal fin is the tail fin,so yes. ^_^

Those are the flippers, or 'pectoral' fins.

The caudal fin or better known as the ¨tail¨ of a fish is used for propulsion (Thrusting forward).

it is called the Caudal Fin
The Tail or Caudal fin.
the caudal fin
An adipose fin is a soft, fleshy fin found on a fish behind the dorsal fin and ahead of the caudal fin.
what do the dorsal and anal fins do for a fish
The tail fin of a fish (the caudal fin) is a fish's means of propulsion through the water.
