Do fishes have teeth?

Have you ever wondered if all the fishes have teeth?
Do they all have the same composition as those of humans?

Fishes have teeth that vary from species to species: some just do not have them, others have many. There are also differences in shape and position: some fishes have them on their palate, others on both jaws, some on their vomer, others on the bones of the pharynx. The shape is usually conical, but in hunting fishes teeth are sharp, resembling to canines.

Fishes which eat algae have incisive-alike teeth: flat and suitable to rip algae and organisms on the seabed. Some other species possess molar teeth, which are ideal for crushing the shells of crustaceans and mollusks. Did you know these differences?โ€จIf you have some more interesting facts to tell us, comment and let us know!
