Black Prickleback

The black prickleback is found from Kodiak Island, Alaska down to northern Baja California. These fish prefer to live in rocky areas with algae cover, mostly in the lower intertidal and shallow subtidal zones. The fish can be found under rocks and in gravel areas, and small ones are common in tidepools. Pricklebacks are capable of breathing air, and can stay out of water for 10-23 hours if they are kept moist by burrowing under seaweed or wet rocks.
