Sebastes rastrelliger
Sebastes rastrelliger is a species of fish in the rockfish family found in tide pools and on rocky bottoms in the Eastern Pacific. It is commonly known as a grass rockfish, grass rockcod, grass bass, or a grassy. It lives in the benthic zone and feeds on crustaceans and small fish. This fish is an ambush predator and waits—hiding in kelp, rocks and holes—until prey passes by. Its coloration can vary from a mottled sandy brown, to a reddish brown to a dark green, depending on where it is holding to structure and feeding.
