The new species of undersea worm S. bombiviridis
was discovered in 2001 as researchers explored deep off California with a remotely operated submersible. Since then, they've found six more Swima
species off western U.S. and Mexico and the Philippine--one of them to be announced in the August 21, 2009, issue of the journal Science.
"If we could get some submersibles down in other places, we would probably find many more species," marine biologist Karen Osborn said.
Paul Yancey, a marine biologist at Whitman College in Washington State, agreed. "We've only explored a few percent of the deep sea, so there's a lot of stuff out there that we haven't found yet," he added.
