The fin on the back of an orca is called the dorsal fin.
the female orca's dorsal fin is curved and the males dorsal fin is straight
An Orca's collapsed dorsal fin will not stand upright while swimming.
The dorsal fin is the fin on the back of a fish, for example the typical triangular fin on the back of a shark is its dorsal fin.
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.
On a dolphin and most fish the fin behind the dorsal fin is the tail fin. Some fish, such as knife fish, have no dorsal fin or tail fin. Dolphins of course are mammals, not fish.
No, a dorsal fin from a fish is on its back area.
The fin on the top/back of all fish is called the "Dorsal Fin."
Some sharks have a second dorsal fin, it's between the main dorsal fin in the middle of the back, and the tail. Not all fish have a second dorsal fin.
well the females live up to 30 years and males live up to 50
No, it is not. Dolphins use their dorsal fin for balance.
The dorsal fin of a dolphin is usefu,l because it can control the balance when a dolphin is swimming.It can also be useful for signs of dolphins and not sharks because the dorsal fin of a dolphin and a shark is slightly different.
