This is a Leptocottus armatus (Staghorn Sculpin) in a plastic container of water. It was brought up in a seine in an educational project at the Port Townsend Marine Science Center. Its little horns kept getting caught on the net, and were difficult to release.
While counting 8,000 + birds on Richardson Bay for our Southern Marin CBC we spotted a Great Egret along the shoreline. It had a good-sized Sculpin, which it fiddled with for 3-4 minutes before gulping it down. Would love to know what species of Sculpin it might have been.
Just learned that this is probably the Pacific Staghorn Sculpin, Leptocottus armatus.
The Pacific staghorn sculpin, Leptocottus armatus, is a common sculpin (Cottidae) found in shallow coastal waters along the Pacific coast from Alaska to Baja California. The sole member of its genus, it is unusual for having spined antler-like projections on its gill covers; it can raise the projections as a defense mechanism.
