Sandy Coast

Appearance

These fish have large and flat heads with small eyes. Their smooth skin is gray-olive on the back, yellow on the sides, and white on the underside. The fins often have barring. These fish are named for the large and branched spine on each operculum, with 3 hooks, which can be raised in defense.

Habitat

Found in shallow coastal waters or in bays and estuaries, usually over sandy or muddy bottoms. Young move up into freshwater in spring and back into the estuary in summer.

Diet

Omnivorous: amphipods, worms, crabs, shrimp, and small fish

Life History

Spawn in salty or brackish water from October to March, with a female releasing 2,000 to 11,000 eggs. It takes about 10 days for the eggs to hatch, with larvae just 0.2 inches long. The larvae spend about 8 weeks as plankton before metamorphosing into the juvenile form. Juveniles may spend some time in freshwater. Maximum length is 18 inches and they rarely live past 3 years.

IUCN Status

Least Concern

Ecosystem & Cultural Importance

These fish feed their predators: larger bony fish, shorebirds, and marine mammals, including seals and sea lions.

Alaska to Baja California, Mexico

These fish might be caught while recreationally fishing from a pier or encountered while tidepooling.

Can breathe air for about 6 hours if stranded during low tide. Will often burrow into the sand or mud with just their head exposed.
