Biology     Glossary (e.g. epibenthic)

One of the specimens (NCSM 41116) represents a new size record for the species (25.5 cm SL, 30.5 cm TL), and another (GMBL 02788) represents a southerly range extension (31°23.94'N). All specimens observed exhibited similar behaviors of sitting on the bottom on top of dense beds of dead coral (Lophelia pertusa) (Ref. 58471).

Estimates based on models

Preferred temperature (Ref. 123201): 4.5 - 14.7, mean 10.5 °C (based on 9 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [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):  4.2   ±0.7 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref. 59153):  Low vulnerability (21 of 100).
