Species Overview
Arapaima
The arapaima is one of the largest freshwater fish in the world, reaching up to 4.5 meters. An obligate air-breather, it must surface every 10-20 minutes to gulp air. Its tongue is bony and used to crush prey against the roof of its mouth.
美国红鱼
The red drum, or redfish, is an iconic inshore game fish of the Atlantic and Gulf coasts. Identified by the distinctive black spot at the base of its tail, it feeds by tipping head-down in shallow water, exposing its copper-colored tail.
