All fishes own teeth. Species like goldfish conceal their pearly teeth beside the bottom of the throat. You call them throat teeth.
Those teeth situate in the throat cavities of the throat at simpletons, cyprinids and many other fish species without visible teeth. Popular aquarium fishes, for instance goldfish and loaches, have such structures. As cyprinids, goldfish bear throat teeth deeply in the throat, bound to the branch bones.
Different Fish Teeth and Where They Are
Many species you identify according to the form of those teeth. By means of them fishes drink and chew the food. Goldfish seem to only take nourishment in the muzzle and chew it inwardly, before spit out the dispersed bits.
Teeth appear in various parts of fish body. Some have them on jaw bones either on the roof of the mouth bones. Others bear tooth patches on the tongue or cushions on gill arches in the throat.
Some fishes entirely lack teeth. Even so you can have sharp lumps on tongue or mouth parts, but no real teeth as at mammals or reptiles. Saltwater fish usually unroll bigger teeth on the jaw than freshwater fish.
Occasionally structures alike to teeth are actually gills or bellies. That happens, when you dig the hooks in the fish lip and itself draws.
You identify teeth according to their form and size. Even species you separate by means of microscopic examination of the wear and slices on them. Between prey-fishes exist three mainstream tooth types: edentulate, villiform and macrodonts.
Tooth form, tooth number, their sequences and relative size helps to identify them. Some fishes have retrorse macrodont teeth, so curving backwards. Canine teeth form long cones, direct or curving, typical for carnivores.
Alligator gar bear two sharp sequences, with the internal longer than the exterior. Shark teeth are very distinctive. They distinctly recognise according to jagged edge with notches and broad root.
Lemon shark teeth measure around 0,75 inches of long. The sheepshead and atlantic wolffish like human teeth between saltwater fish. Some folks err mixing the freshwater pacu with marine species because of its humanlike teeth.
