Épines dorsales (Total) : 2; Épines anales: 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).

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).

Niveau trophique (Ref. 69278): 4.5 ±0.80 se; based on food items.

Résilience (Ref. 120179): Très faible, temps minimum de doublement de population supérieur à 14 ans (Fec=1).

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