The Atlantic tarpon (Megalops atlanticus) is a ray-finned fish that inhabits coastal waters, estuaries, lagoons, and rivers.It is also known as the silver king.It is found in the Atlantic Ocean, typically in tropical and subtropical regions, though it has been reported as far north as Nova Scotia and the Atlantic coast of southern France, and as far south as Argentina.
Tarpon grow to about 4–8 ft (1.2–2.4 m) long and weigh 60–280 lb (27–127 kg). They have dorsal and anal soft rays and bluish or greenish backs. Tarpons ...
In appearance, it is like the much larger Atlantic tarpon, M. atlanticus - olive-green on top, and silver on the sides. The large mouth is turned upwards; the lower jaw contains an elongated, bony plate. The last ray of the dorsal fin is much longer than the others, reaching nearly to the tail.
The mouth may be modified into a suckermouth adapted for clinging onto objects in fast-moving water. The simpler structure is found in jawless fish, in which the cranium is represented by a trough-like basket of cartilaginous elements only partially enclosing the brain and associated with the capsules for the inner ears and the single nostril.
Unlike humans, fish have little or nothing in the way of a tongue, and those that have such an organ do not use it for tasting, but merely for cushioning the mouth and manipulating things within it. The papillae of the fish, and the taste buds found on them, are therefore located on the interior or exterior surfaces of the mouth. [ 2 ]

A typical radula comprises a number of bilaterally-symmetrical self-similar rows of teeth rooted in a radular membrane in the floor of their mouth cavity. Some species have teeth that bend with the membrane as it moves over the odontophore, whereas in other species, the teeth are firmly rooted in place, and the entire radular structure moves as one entity.
