Small molted grey, brown and white sculpin. They can change their color rapidly so as to camouflage itself.
Spotted in a tide pool at Tongue Point Marine Sanctuary.
It is a predator, feeding on small invertebrates such as isopods, amphipods, gastropod molluscs, polychaete worms and barnacles, as well as insects that happen to fall into the water. Small amounts of algae also form part of the diet. Sculpins are preyed upon by diving birds and by predatory fishes when the tide is high. (Wikipedia)
