Their number is variable, and depends on the size of the animal, its age. Some time back the tooth is in the gum, taking a vertical position only when the free space because, unlike the teeth of mammals, they do not have long roots and they are able to move about freely in the gums.

The porbeagle teeth tone, acute and recurved for grasping and retaining a nimble and slippery prey. In benthic species, feeding on molluscs and crabs, the teeth are thick and blunt – these tools comfortable to chew solid calcareous shell and the shell. The teeth are in the mouth and in the throat of many series – one thousand and even more. Working teeth are in the front row. They easily fall off, and his successor shall be nominated from the depths of the jaws of the all-new series is a real “factory tooth”.

Teeth amelialewis the most terrible of its weapons, although some species of sharks have no teeth,for example, the basking shark. Large hunters such as great white and tiger sharks, the teeth are large, triangular with serrated edges that enhance tenacity and strength. Almost all species of sharks, the teeth are directed inwardly, except for the victim the opportunity to escape from the jaws. In both jaws the teeth grow in rows, constantly renewing, starting from the back row. Shark teeth located in their jaws straight rows, sometimes a thousand or more teeth in a row

Like other fish, sharks get the oxygen it needs from water by passing it through the gills. The organs of respiration are branchial pouches, which have internal Gill openings open into the throat, and outer − sides of the head onto the body surface.

Each species has its own lifespan, and difficult to appreciate it for all the sharks.

They were small teeth belonging to individuals of the length, apparently, not more than 30 cm Despite the relative rarity of attacks, fear of them has grown thanks to the descriptions of individual cases, such as the attack at the Jersey shore in 1916, when 4 people died and 1 were injured, as well as literary works and horror films like the film series “Jaws”.
