The newly discovered green, glowing balloon-shaped bombs--shown here on a new Swima undersea worm species--are each about the size of a pinhead. The seven known Swima species range from 0.7 to 3.6 inches (18 to 93 millimeters) long.

The distracting bombs are attached near the worms' heads. After dropping a bomb, a worm swims away backward, marine biologist Karen Osborn said in August 2009. This allows most of its body to quickly escape a predator's range.
