Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 2; Anal spines: 0. Conspicuous black tips on dorsal fins, black dorsal caudal margin, black ventral caudal lobe (Ref. 247).

Found on the insular slopes (Ref. 247). Feeds on lanternfishes, boarfishes, barracudinas, and flatheads (Ref. 247). Probably ovoviviparous (Ref. 247). Defends themselves from their captors by whipping their bodies and long second dorsal spines (Ref. 247).

Distinct pairing with embrace (Ref. 205).

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=0.00339 (0.00162 - 0.00707), b=3.10 (2.93 - 3.27), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.5 ±0.80 se; based on food items.

Resilience (Ref. 120179): Very Low, minimum population doubling time more than 14 years (Fec=1).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (50 of 100).
