Morphology | Morphometrics
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).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02455 (0.01114 - 0.05408), b=2.90 (2.72 - 3.08), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.5 ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (30 of 100) .
