Short description
Morfologia | Morfometria
Spine dorsali (totale): 2; Raggi dorsali molli (totale): 0; Spine anali 0; Raggi anali molli: 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): PD
50 = 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.
Resilienza (Ref.
120179): Molto basso, tempo minimo di raddoppiamento della popolazione più di 14 anni (Fec=1).
Fishing Vulnerability (Ref.
59153): Moderate to high vulnerability (50 of 100).
