ການຖ່າຍທອດທາງກຳມະພັນຈາກພໍ່ແມ່ຫາລູກ 2; ຄີກົ້ນຂອງປາ: 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).
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).

50 = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02570 (0.01193 - 0.05536), b=2.88 (2.71 - 3.05), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
ຊັ້ນເຂດຮ້ອນ (Ref.
69278): 3.6 ±0.50 se; based on food items.
Generation time: 4.5 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
ຄວາມຢືດຢຸ່ນ (Ref.
