Morphology | Morphometrics
(total): 2. Small ventral light organ, lacking a dermal window; ventral surface of head and lower jaw covered with small spinulated scales; dorsal surface of head with scales except for small naked anterior lateral areas; snout short, 33.7% HL, armed with terminal and lateral scutes; orbit large 37.9% HL; scales armed with rows of low, parallel spinules, with spinule rows overlapping hind margin of scale; 10 gill rakers on inner side of first arch; margin of upper lip dark brown (Ref. 26363).
Probably inhabits areas not suitable for sampling with a bottom trawl (Ref. 26363).

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 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), based on all LWR estimates for this body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.5 ±0.5 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Moderate vulnerability (38 of 100) .
