Appearance

These slim fish are brassy brown on their back and sides, and a lighter, dusky brown ventrally.

Habitat

Usually found above hard bottoms on the continental shelf, including rocky banks, sea mounts, canyons, and muddy bottoms near rocks, to depths of 2,625 feet.

Diet

Sergestid shrimp are their primary prey in winter, salps are their most important prey item in spring, and fish are most important in fall.

Life History

Mating mostly occurs in December in Oregon. Females then release their larvae from February to March. A 12 inch female will release 55,000 young while a 20 inch female will release 915,000 young. The pelagic larvae are just 2 inches at birth and remain pelagic as juveniles, settling to subtidal structures, including rocks, kelp, and oil platforms when they are between 2-3 inches long, usually from May to September.

Grow to 24 inches and live to at least 60 years.
