Vertebrae: 137 - 148. This species is distinguished by the following characters: tail 52% and head 11-14% of TL; body cylindrical for most of its length; dorsal fin arising well behind pectoral-fin tips; pectoral fins moderately elongate, about 3-6 times in HL; snout moderate; about 3.0 in jaw; jaws elongate, about 2.1-3.0 in head; lower jaw extending beyond snout tip; nostrils in very short tubes in upper lip and closely associated; cirri of labial fringe minute on lips of subadults, absent in large adults; center of eye behind anterior 30% of jaw; interorbital space narrow, less than orbit width; dorsal head profile nearly flat from level of midjaw to snout tip; nape and cheeks swollen, narrowing anteriorly from level of midjaw; cephalic pores inconspicuous; free sensory neuromasts not visible on nape; teeth conical; purplish brown when alive; lateral-line and cephalic pores (except mandibular) surrounded by fine dark punctations.
Observed nearly fully buried within a muddy bottom at a depth of 20 m (Ref. 42180).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00091 (0.00039 - 0.00215), b=2.99 (2.79 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 4.1 ±0.6 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.).
Fishing Vulnerability (Ref.
59153): Very high vulnerability (78 of 100).
