Floating eerily through the hazy depths of the ocean, this creature looks like it came straight out of science fiction movie The Abyss.
The sight was captured by remotely operated underwater cameras, although the location is uncertain.
But a more likely explanation is that the pulsing, billowing creature is a type of jellyfish known as Deepstaria enigmatica.
According to the Marine Species Identification Portal, the Deepstaria enigmatica is found in the South Atlantic Ocean, with a bell that can measure up to 60cm in diameter.
It has “oral arms” which end in “curious hook-shaped organs”.
