(Cannon Beach, OR) -- Marine biologists are studying a squid that washed up on an Oregon beach. The Oregonian reports that the ten-foot-long, 90-pound clubhook squid is a rarity in the Pacific Northwest. It reportedly hit the shore late last month at Silver Point, just south of Cannon Beach. Seaside Aquarium's manager said it was the first one he's ever seen. It's not clear how the squid died, but marine experts say they often die after laying eggs.
