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.
Spotted Seatrout
The spotted seatrout, despite its name, is a member of the drum family, not the trout family. It inhabits grass flats and estuaries along the Atlantic and Gulf coasts. Males produce a distinctive drumming sound to attract females.
