Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 121 - 139; Anal soft rays: 91 - 102; Vertebrae: 71 - 78. This species is distinguished by the following set of characters: dorsal-fin rays 121-139; anal-fin rays 91-102; total vertebrae 71-78; otolith ostium depth 30-40% of sulcus length (Ref. 80689).

Biology     Glossary (e.g. epibenthic)

One specimen from the eastern Pacific was examined and radiographs showed the following stomach contents: detritus, gastropods, crustaceans, ophiurids, remains of polychaetes, foraminifera, sediment, and bivalves. From individuals with filled stomachs), detritus was found to be 88%, followed by gastropods (52%), crustaceans (44%), and ophiurids (36%). Observed ontogenetic trend in the consumption of gastropods with 18.2% in specimens less than 45 cm SL (n=11) and 78.6% in specimens greater than 45 cm SL (n=14, Fisher’s Exact Test, P<0.005); all gastropod shells were intact (Ref. 80689).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.7500   [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 to high vulnerability (48 of 100).
