black marlin

The black marlin (Istiompax indica) is a large billfish found in the Pacific and Indian Oceans. It is characterized by its dark blue upper body and silvery-white underside. Black marlins can grow to impressive sizes, reaching lengths of about 15 feet (4.6 meters) and weights of up to 1,650 pounds (748 kilograms).1

Marlins, in general, are marine fish known for their elongated bodies, long dorsal fins, and a spear-like projection from their snout. They are carnivorous, feeding on other fish, and are highly regarded by sport anglers. The black marlin is one of four generally accepted valid species of marlin, alongside the blue, striped, and white marlins.2
