Alternative names: Megalops
Tarpons large air-breathing fish that can be found in the Atlantic and Indo-Pacific oceans. Thanks to it's splendid grey color, the Tarpon is also called "The silver king".
Unlike most of the fishes, the Tarpon posses swim bladder which works like a lung so they can breath air.
In Florida the people catch the fish for pure pleasure and then they either free it or keep it as a trophy.
