Camera lights in the perennially dark depths of the Coral Sea reveal an atolla jellyfish's true colors in a 2006 picture.
During the ongoing Deep Australia Project, researchers have snapped a variety of odd creatures, including "prehistoric" six-gilled sharks, giant oil fish, swarms of crustaceans, and many unidentified fish.

A deep-sea anglerfish feels—rather than sees—the remote camera that took its picture in 2006.
Lined with sensory studs, the fish's flanks detect vibrations that allow it to live and love in the endless dark of the Osprey Reef, about 6,500 feet (2,000 meters) beneath the Coral Sea.
