Weird News: Gelatinous sea creatures wash up in Washington

SEATTLE — The same gelatinous sea creatures that clogged the intake at California's Diablo Canyon nuclear power plant last spring have shown up this winter on the Washington coast, marine life experts say.The harmless jellyfish-like animals are called salps.They've been found by clam diggers and turned up in the pots of crab fishermen who have been asking what they are, said state Fish and Wildlife Department biologist Dan Ayres at Montesano.He hasn't seen them in more than 30 years and says their appearance now is unusual, but not alarming."I suspect these guys came from the deep ocean," Ayres said Wednesday. "Why they've been washed up is a question I can't answer."Salps are common in the blue water off Oregon and Washington, said Rick Brodeur, an oceanographer known as the "jellyfish person" at the National Oceanic and Atmospheric Administration's Northwest Science Center in Newport, Ore.
