Maturiteit: Lm ? range ? - ? cm
Max length : 40.0 cm TL mannelijk / geslacht onbekend; (Ref. 81679)
Dorsale stekels (totaal) : 0; Dorsale zachte stralen (totaal) : 11 - 12; Anale zachte stralen: 9 - 10; Wervels: 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).
Body shape (shape guide): short and / or deep; Cross section: circular.
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).
