The Atlantic tarpon, Megalops atlanticus, is a large coastal fish prized by anglers. The Atlantic tarpon is also known as the silver king. They grow up to 8 feet in length and sometimes weigh 200 pounds.
When swimming in oxygen-poor water, tarpons can breathe air from the surface. Tarpon are superb sport, with a long-lasting, powerful fight generally including several leaps. While edible, they are seldom eaten, as their flesh is considered too oily to be palatable.
The body is greenish or bluish on top, and silver on the sides. The large mouth is turned upwards, and 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 Atlantic tarpon is found in the Atlantic ocean typically in tropical and subtropical regions, though it has been reported as far north as Nova Scotia and as far south as Argentina. Diet includes smaller fish and crustaceans.
