It steers and helps with stability
The dorsal fin is the fin on the back of a swimming animal's body. It helps the creature steer through the water like a rudder. A orca, or killer whale, has a very tall dorsal fin. The dorsal fin of the male is taller than the dorsal fin of the female. The male's dorsal fin can reach a height of seven feet, while the female's fin can be 5 feet tall. Killer whales in the wild have dorsal fins that stick straight up in the air. Almost all killer whales in capitivity have dorsal fins that droop over like a floppy dog's ear.
