This large species (to 122 cm TL) is distinguished by the following set of characters (based on the unique holotype specimen): strongly depressed and quadrangular disc with narrowly rounded apices, width 64% TL, 1.1 times its length; rather short tail, its length 0.8 in distance from snout tip to rear of cloaca, and width 1.8 times height at its midlength, 1.5 times at first dorsal-fin origin; pre-upper jaw length 18% TL, which is 2.3 times internasal width; ventral head length 32% TL; long and broad snout, length 4.0 times interorbital width, supported by slender flexible median cartilage; angle of snout 83°; narrow mouth 7% TL; orbit diameter 57% interorbital width; first dorsal-fin height is 1.7 in its base length; procaudal length 2.3 times first dorsal-fin base length, 4.8 times caudal-fin length; dorsal disc and almost entirely devoid of fine denticles; disc thornless, other than narrow alar thorn patches; tail with 16 (one lost) thorns in single median row; total pectoral radials 84-85; trunk centra 34; predorsal centra 105; total centra ca. 136; tooth rows in upper jaw 29; the skin is thin and almost entirely translucent white, no dark areas on body, sensory pores indistinct (not dark edged) (Ref. 110384).

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=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
营养阶层 (Ref. 69278):  4.0   ±0.7 se; based on size and trophs of closest relatives
回复力 (Ref. 120179):  非常低的, 最小族群倍增时间超过14 年 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  High to very high vulnerability (73 of 100).
