Bizarre sea creatures wash ashore off Washington coast

Tropical sea creatures called pyrosomes have arrived off the coast of Washington -- and experts are seriously concerned it could mean trouble for the fishing industry.

"I'm familiar with them, but I've never seen them up here in the Pacific Northwest. I'm surprised," one scientist told KCPQ.

The cucumber-like animals are pretty small on their own, but when they come together, they create giant organisms that are more than 20 feet long.

Fishermen are already complaining that there are so many pyrosomes gathering off the shore, they're gumming up fishing lines, hooks and cages.
