Description synthétique
Morphologie | Morphométrie
Épines dorsales (Total): 0; Rayons mous dorsaux (Total): 11-12; Rayons mous anaux: 9 - 10; Vertèbres: 18 - 19. Diagnosis: caudal fin truncated or slightly emarginate, its length comprised about 4 times in SL; black-rimmed red ocelli (eyespots) on sides of adults (Ref. 57417).
Juveniles and adults are common in the mainstream river (Ref. 2829). Ventral pocket communicates gill chamber with oesophagus, allowing the fish to inflate its body like a ball (Ref. 57417). Liver and sexual organs are poisonous, but fishermen of the upper Cross carefully remove them and eat the flesh of this species (Ref. 81679). Some references to Tetraodon guttifer in the literature may represent misidentifications of T. pustulatus (Ref. 81679).
