The kelp bass, sometimes referred to as the calico bass, is a species found in the eastern North Pacific Ocean from Baja California, Mexico, to Washington, USA. As suggested by its common name, it is typically associated with kelp beds, but may also be found in rocky areas or near hard structures. It prefers relatively shallow water, but may occur as deep as 165 ft. It feeds on small fishes, squid, crustaceans, and, when abundant, plankton. During the warmer months (May to September in California), kelp bass form spawning groups in deeper water. After one to two days, the pelagic eggs hatch into larvae, which metamorph into juveniles after about a month.
