A swordfish has a fin on its back.
No, a dorsal fin from a fish is on its back area.
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.
Dorsal (fin).
The fin on the top/back of all fish is called the "Dorsal Fin."
The Dorsal Fin is located on the "back" of a fish. Where the spine is.
yes
it is the fin on the top near the back of the fish
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.

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.
Depending on the damage, a fin can grow back provided the fish is cared for properly and the water is clean
I think that the largest fin of a perch is the first dorsal fin, the one that is located on the top of the fish and is spiny.
