Glowing 'bomber worms' discovered

A group of glowing worms has been found dwelling in the deep ocean, some of which release body parts as tiny "bombs" to ward off predators.

Lead author Karen Osborn, from the University of California San Diego, told BBC News that she and her colleagues found the worms accidentally, whilst exploring the deep oceans with remotely operated submersible vehicles.

The Prettiest Bomb You Ever Did See

Thousands of meters below the sea, a tiny worm wriggles through the darkness, its dozens of paddle-shaped bristles moving in beautiful coordination. Suddenly, a hungry predator appears. The worm releases a glowing green sac, and the fish homes in on this bright new trophy. By the time the fish realizes the sac is no meal, the worm is long gone.
