Silent scream

When attacked by a predator, this deep-sea jellyfish (Atolla wyvillei) uses bioluminescence to "scream" for help. The amazing light show is known as a burglar alarm display. This jellyfish was photographed by the ROV Hyper Dolphin east of Japan's Izu-Oshima Island, 2,640 feet (805 meters) below the surface.

Diversity in the deep

The Census of Marine Life is aimed at cataloging as many species of sea creatures as possible. This is a Venus flytrap sea anemone (Actinoscyphia sp.) from the Gulf of Mexico. Its common name includes references to two terrestrial plants ("Venus flytrap" and "anemone"), but the species is classified as a type of polyp. It closes its tentacles to capture prey or protect itself.

Cooper of the Sea

This Gulf of Mexico amphipod, Phronoma sedentaria, is known as the "Cooper of the Sea" because the crustacean species lives inside a barrel-shaped creature known as a salp, also shown here.

Paper bubble
