Biology     Glossary (e.g. epibenthic)

Live in surf on sand beaches and over sand near rocks, often around piers. Often occur in dense schools. Feed on small crustaceans. Viviparous, female carries the developing young (Ref. 205). Usually bear 5-12 young. An important game species.

Estimates based on models

Preferred temperature (Ref. 123201): 10.7 - 19, mean 12.8 °C (based on 115 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.6250   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01905 (0.00831 - 0.04372), b=2.97 (2.77 - 3.17), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.5   ±0.50 se; based on food items.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (tm=1; tmax=6).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (20 of 100).
