Short description
Identification keys | Morphology | Morphometrics
This species is distinguished from its congeners by the following set of characters: snout is moderately long, sharply pointed in lateral and dorsal views, its length 39–42% of head length; lateral nasal ridge is completely supported by nasal bone; light organ is short, with length less than 1/2 orbit diameter, its anterior margin falling far short of pelvic-fin bases; premaxillary teeth in short, uniformly wide band, with the posterior end of the tooth band not reaching lateral corner of mouth; teeth not greatly enlarged; body scales are covered with short, reclined, narrowly blade-like spinules in widely divergent rows; buttresses of body scale spinules are scarcely developed; occipital scales between parietal ridges armed with divergent rows of long, erect, and needle-like spinules; nasal fossa usually naked (a few small scales rarely present anteroventrally); patches of small scales sparsely distributed on the ventral surface of head; scales on underside of head armed with 1-3 rows of short, erect, needle-like to knife-like spinules; interdorsal space is longer than first dorsal-fin base length; subopercle terminating as a long, slender flap; body dark overall with no prominent markings; fins are uniformly blackish (Ref. 129407).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = No PD50 data [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00245 (0.00126 - 0.00477), b=3.19 (3.02 - 3.36), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.6 ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low to moderate vulnerability (32 of 100).
