"Fin fish" are true fish. They are vertebrates, like us, and belong to the phylum chordata.
Shellfish are not really fish. The term refers to a vareity of shelled aquatic invertebrates, primarily crustaceans and molluscs.
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.
fish have scales and crabs have a shell
The difference is that sailfishes have a long, sail-like dorsal fin which stretches through the whole back while swordfishes have just a tiny shark-shaped dorsal fin.
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.
The tail fin of a fish (the caudal fin) is a fish's means of propulsion through the water.
The fin on the top/back of all fish is called the "Dorsal Fin."
No, a dorsal fin from a fish is on its back area.
Most fish typically have 7 fins in total. - The dorsal fin. Prevents fish from rolling. - Adipose Fin. Makes the fish hydrodynamic. - Caudal Fin (tail). Propels the fish through the water. - Pectoral fin (x2). helps the fish steer and halt. - Pelvic fin. Helps the fish steer and halt. - Anal fin. Keeps the fish from rolling.
Most species of fish don't have an adipose fin.
There are literally hundreds of species of fish that have a red fin.
