Description synthétique Clés d'identification | Morphologie | Morphométrie

Differs from its congeners by a combination of the following characters: caudal peduncle quadrangular in cross-section; adipose-fin origin vertically crossing middle length of last anal-fin ray; arrector fossae opening on each side of scapular bridge occupying one fourth to two fifths of distance from mid-ventral suture of scapular bridge to its lateral margin; abdomen totally covered with 5-7 elongated plates on each lateral series and 7-10 series between them; eye small, 2.1-2.5 times in interorbital distance; plates in longitudinal series 24-26; adult individuals measuring up to 2.7 cm SL with 22-27 premaxillary teeth and 21-24 dentary teeth (Ref. 57861).

Facultative air-breathing in the genus (Ref. 126274)

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00759 (0.00337 - 0.01709), b=3.12 (2.93 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
