Morphology | Morphometrics
soft rays: 93;
Vertebrae: 65. Snout inflated; eyes much smaller than snout; opercular spine weak or absent; preopercle without spines and posteriorly expanded almost reaching posterior margin of opercle; pseudobranchial filaments 2 (Ref. 34024).
Specimens were apparently caught on or near the bottom at abyssal depths (Ref. 84269). Rare species (Ref. 34024). Reproductive strategy possibly similar to other members of this family featuring oviparity, with oval pelagic eggs floating in a gelatinous mass (Ref. 205).

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5001 [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
): 3.8 ±0.6 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): High vulnerability (59 of 100) .
