The anal fin, is used to stabilize the fish while it is swimming.in some fishes such as trigger fishes.anal fin is used in sculling.in some live-bearinf fish,the anal fin of male is modified into a gonopodium.
The caudal fin, more often called the tail, is used for propulsion.
a dorsal fin is the one (or more) located on the back of a fish or aquatic mammal - its the fin that you see when a shark is swimming just under the surface of the water. Ventral fins are the ones toward the rear of the body and help in steering the animal through the water
