Mysterious Deep Sea Creature and Diverse Comb Jellies Unveiled.
A video clip of a deep-sea creature that has been described as an "alien-looking creature" or "unidentified transforming deep sea creature" is actually a bloody-belly comb jelly, or Lampocteis cruentiventer, a species that is often photographed during deep-ocean ROV missions. The species is found throughout the Pacific Ocean basin and has been seen in the Atlantic Ocean basin as well. The reddish tint of the translucent comb jelly's body is believed to hide the contents of its stomach from predators, and in the deep sea, the jelly appears black, rendering it virtually invisible given the darkness of its surroundings.
