Pacific staghorn sculpin
📖 Overview
Commonly found near shore, especially in bays and estuaries; most frequently on sandy bottom . Intertidal individuals breath air when out of water . Can leave tide pools if aquatic conditions become inhospitable . Although some individuals may spend their entire life in highly saline waters , some newly metamorphosed young move from the estuarine spawning sites to completely fresh water and may remain there for up to 6 weeks . Adults apparently tend to remain in the shallow lower estuary, or farther offshore . Feeds mostly on crabs, shrimps and amphipods, but also takes larval, juvenile and adult fishes, as well as polychaete worms, mollusks and other invertebrates . Expands its gill covers and produces a low-pitched humming sound when stressed . Considered a nuisance by anglers .
