Biology     Glossary (e.g. epibenthic)

Uncommon species (Ref. 34024). Free-living adults are found on the outer shelf, usually deeper than 64 m over muddy sand bottoms (Ref. 36487). Oviparous, with specialized vexillifer planktonic larval stage, and benthic tenuis larval stage (Ref. 36487). Maximum depth from Ref. 58018.

Estimates based on models

Preferred temperature (Ref. 123201): 14.6 - 20.3, mean 17.1 °C (based on 6 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5001   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00102 (0.00046 - 0.00225), b=3.06 (2.88 - 3.24), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.5   ±0.5 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
