Eyes superolateral; frontal fontanelle long and narrow; occipital fontanelle oval-shaped; head completely covered with bones; suprabranchial organ well developed; tooth plates relatively narrow; openings of secondary sensory canals regularly placed (Ref. 270). Coloration: preserved specimens: grey, greyish-brown to dark brown on back and sides, pale brown on belly; some individuals show a marbled colour pattern; caudal and adipose fins uniformly coloured (Ref. 57129).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00851 (0.00489 - 0.01483), b=2.91 (2.76 - 3.06), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

ຊັ້ນເຂດຮ້ອນ (Ref. 69278): 3.7 ±0.7 se; based on size and trophs of closest relatives
