Tide Pool Sculpin – (Oligocottus maculosus): The tide pool sculpin, also known as Oligocottus maculosus, is a very common fish from the Sea of Okhotsk, Russia to the Bering Sea, Alaska, and down the Eastern Pacific to Southern California. Though these fish only reach about 3.5 inches and live a maximum of five years, they thrive in the turbulent waters of the intertidal zone. They also have the ability to withstand very cold-water temperatures. In the Bering Sea they have been known to live in temperatures as low as 33 degrees Fahrenheit. Other interesting characteristics of this species, is their uncanny ability to find their way back to their favorite tide pool as well as the fact they have no scales. Tide pool sculpin survive by eating isopods, amphipods, shrimp and worms. In turn, they are often eaten by larger fish like the kelp greenling. They range in coloration from gray to brown and even green with multi-colored speckles
