  • The arapaima has a fundamental dependence on surface air to breathe. (ref: Wiki)
  • In addition to gills, it has a modified and enlarged swim bladder, composed of lung-like tissue, which enables it to extract oxygen from the air. (ref: Wiki)
  • The arapaima male is supposed to be a mouthbrooder, like his relative, the Osteoglossum, meaning the young are protected in his mouth until they are older. (ref: Wiki)
  • Arapaima is NOT a mouthbrooder (ref: FAO)
  • W = 3.788E-05* L ^2.7045 (ref: FAO)
