Widow rockfish are a lateraly compressed species with a small mouth and weak head spines. Adults display a shiny copper, brass or brown color with large lighter blotches evident in younger individuals.
They will usually congregate in large schools well above bottom structure, sometimes swimming together with Blue and Yellowtail rockfishes. Widows range from the western Gulf of Alaska, south to northern Baja California, but are most abundant from B.C. Canada to northern California. This species reaches a maximum length of nearly 2 feet.
The Widow’s name, entomelas, Greek meaning “within” and “black”, refers to the black lined gut cavity.
