Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 13-15; Anal spines: 0; Anal soft rays: 8 - 10. Black in color (Ref. 5320).

Biology     Glossary (e.g. epibenthic)

Common on mid and lower continental slope. Rests on the bottom with the use of elongated, stiffened outer pelvic and lower caudal fin rays (tripod). Sensory pectoral fins are thrown forward in front of its head, facing the current. Feeds on benthopelagic plankton. Synchronously hermaphroditic (Ref. 6688). Spawning is seasonal with peak during fall in the Bahamas (Ref. 3590).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00490 (0.00193 - 0.01241), b=3.03 (2.81 - 3.25), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.4   ±0.45 se; Based on food items.
Resilience (Ref. 69278):  Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Moderate to high vulnerability (49 of 100) .
