Thousands of feet beneath the sea live worms that can cast off green glowing body parts, a move scientists think may be a defensive effort to confuse attackers. Researchers have dubbed the newly discovered critters “green bombers.” The seven new species of worms were found by a team led by Karen Osborn of the Scripps Institution of Oceanography at the University of California, San Diego. Ranging in size from three-fourths of an inch to nearly four inches, the worms live at depths of 5,900 feet to more than 12,000 feet. They have appendages, which they release when they are disturbed, she said. Once release the appendage, it glows bright green.
