Description

The tidepool sculpin is a sculpin (Cottidae) from the northeastern Pacific. The species is small, scaleless and variably coloured in green, brown or red, matched to its surroundings. It is a permanent resident of tide pools and has a strong homing instinct: when moved, it finds its way back to its own pool. As a bottom hunter it feeds on small crustaceans, snails and worms. The species is harmless to humans.
