Fish with pectoral fins use them to swim around, much like you would use flippers on your feet in the water
The pectoral fin mantains how deep the fish can go.
The pectoral fin on a shark helps with steering and stability while swimming.
A fish has several different types of fins. There are the pectoral fins, located beneath the operculum (gills). There is the pelvic fin, located at the bottom of the fish, below the pectoral fin. There is the anal fin, which i located behind the anus, and there is the dorsal fin as well. It is located on top of the fish.
On the side of the fish
The pectoral fins in both sharks and body fish are Lateral, which refers to them being located on the sides. Ventral would mean that the fins are on the bottom of the fish, which is not true.
The pelvic fin is in the bottom; toward the front side of the middle. The pectoral fin is on the bottom, in the front. The pectoral fin helps control the direction the perch moves. The pelvic fin also controls the direction it moves. The anal fin is in the bottom back side and helps the fish balance. The dorsal fins are on top, one in the middle one it the back and stabalize the fish and aid in sharp turns. The caudal fin, or the tail, is in the back and helps to propel the fish through the water.
A whale's pectoral fin helps with steering, stability, and balance during daily activities like swimming and hunting for food.
2 fins
Every fin a fish has is there for a purpose. Of course the pectoral fins help them swim. They can also be used as brakes.
The tail fins are 'flukes'. Otherwise the fin on any marine animal is "... fin" where "..,." is the adjective denoting its position on the body.
