Wild arapaima are harpooned or caught in large nets. The Arapaima fish's outer scales are designed to resist piranha bites. Prominent species include the Giant otter, the Harpy eagle and the Arapaima. Member species of the genus "Arapaima" are the largest freshwater fish in South America. "Arapaima" was traditionally regarded as a monotypic genus, but later several species were distinguished. As a result of overfishing, large arapaima more than are seldom found in the wild. The arapaima is torpedo-shaped with large blackish-green scales and red markings. Arapaima produce boneless steaks and are considered a delicacy. Like other members of the genus "Arapaima", this fish can breathe air. Genus "Arapaima" is the type genus of the family Arapaimidae. The arapaima was introduced for fishing in Thailand and Malaysia. The arapaima has a fundamental dependence on surface air to breathe. It is the first new member of "Arapaima" to be described since 1847. Arapaima is used in many ways by local human populations.
