Dear student,

Unpaired fins | Paired fins |
In the majority of fishes,there are paired or median fins present. These include one, two, or three dorsal fins, a distinct tail fin, and an anal fin. | The paired fins in the fishes include the pectoral fins, placed just back of the gills, and the pelvic, or ventral, fins, variable in position and sometimes entirely lacking. |
These fins helps in changing direction and maintaining the speed of swimming. |
These fins are used for steering, balancing, and for slow movements. |
