Short description Identification keys | Morphology | Morphometrics

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).

Occurs on or near the bottom at continental slope 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). A female specimen caught was with 0.5 mm eggs (Ref. 84269).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 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), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.7 ±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): Moderate vulnerability (42 of 100).
