The giant jellyfish with arms grasping deep sea equipment.
Remarkable footage of a rarely seen giant deep sea jellyfish has been recorded by scientists.
Using a remotely operated vehicle (ROV), they captured a video of the huge Stygiomedusa gigantea.
The jellyfish has a disc-shaped bell than can be a metre wide, and has four arms that extend up to six metres in length.
The jellyfish has only been seen 114 times in the 110 years it has been known to science, say researchers.
Professor Mark Benfield from Louisiana State University in Baton Rouge, US, came across the creature as part of the Serpent project, a collaboration between marine scientists and energy companies, including BP, Shell, Chevron and Petrobras, working in the Gulf of Mexico.
Using ROVs provided by the oil and gas companies, scientists are able to explore the deep ocean in more detail, including the so-called mesopelagic and bathypelagic layers of the sea.
In a similar study, researchers recently captured footage of one of the ocean's largest fish, the serpent-like oarfish.
Not much is known about the jellyfish, but it is thought to be one of the largest invertebrate predators in the deep sea ecosystem.
