The Atlantic tarpon, Megalops atlanticus, is a large, powerful fish found in warm coastal waters, estuaries, and lagoons of the Atlantic Ocean. Known for its shiny, silver scales and ability to leap out of the water, it is a popular target for sport fishing. Tarpon are often found near the surface and feed primarily on smaller fish and crustaceans. They are capable of breathing air, allowing them to survive in low-oxygen environments.
