(ăr'əpī`mə), tropical fish, genus Arapaima, of the Amazon basin. Arapaimas are perhaps the largest of the strictly freshwater fishes, reportedly reaching a length of 15 ft (4.5 m), but averaging 7 to 8 ft (2–2.4 m) in length and 200 lb (90 kg) in weight. The dorsal and anal fins of the arapaimas are placed so far back that they appear to be part of the tail fin, giving a massive appearance to the posterior region. The scales are olive-green, turning increasingly reddish in the tail region and becoming crimson near the tail fin. The swim bladderswim bladder,
