Short description Morfologia | Morfometria

Spine dorsali (totale): 2 - 3; Raggi dorsali molli (totale): 9-10; Spine anali 2; Raggi anali molli: 7 - 8. Diagnosis: skin scaleless, but head and body covered with small spines except on snout and caudal region; teeth form beak-like structure consisting in each jaw of two pieces fused on midline and covered by layer of enamel; nostrils consisting of two fleshy lobes placed in front of folded collar surrounding the opening; two pairs of non-perforated nasal tentacles; dorsal and anal fins short and placed far back on body; pectoral fins well developed; no pelvic fins; caudal fin rounded, its length comprised 3 times in SL; longitudinal stripes along sides of body in adults; black-rimmed red ocelli (eyespots) present in juveniles (Ref. 57417).

Biologia     Glossario (es. epibenthic)

Found in large rivers (Ref. 2829), open water, weed beds and vegetated fringes; feeds on mollusks (Ref. 28714). Ventral pocket communicates gill chamber with oesophagus, allowing fish to inflate its body like a ball (Ref. 57417).

Estimates based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5020   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02754 (0.01273 - 0.05959), b=2.88 (2.70 - 3.06), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.6   ±0.50 se; Based on food items.
Resilienza (Ref. 120179):  Medio, tempo minimo di raddoppiamento della popolazione 1.4 - 4.4 anni (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low to moderate vulnerability (31 of 100) .
