Giant phantom jellyfish
The mouth arms of the phantom jellyfish trail behind it like scarves in the wind.

In November, MBARI released rare video footage of a giant phantom jellyfish (Stygiomedusa gigantea). Scientists operating an ROV at a depth of 3,200 feet (975 m) in Monterey Bay, California, spotted the massive jelly, with its 3.3-foot-wide (1 m) bell and 33-foot-long (10 m) ribbon-like arms.
Not much is known about phantom jellyfish, but scientists think it uses its arms, which stream like loose scarves in its wake, to ensnare unfortunate prey and winch them up to its mouth. The creature also propels itself through the pitch-black depths with periodic pulses from its faintly glowing bell.
"The giant phantom jelly was first collected in 1899. Since then, scientists have only encountered this animal about 100 times," MBARI said in a statement. Although it is rarely spotted, the jelly has been found in the depths of every major ocean in the world, except for the Arctic Ocean.
