Far out at sea, a gaggle of marine biologists are gathered round a display. A pinky-purple blob swims out from the gloom and floats into view. “That’s superb!” exclaims considered one of them. However what’s it?
Utilizing a remotely operated automobile, they’ve filmed what is usually often called a headless hen monster (Enypniastes eximia). This deep-sea creature is a sea cucumber however can be known as a ‘Spanish dancer’ as a consequence of its sleek actions.
Whereas many sea cucumbers can swim, most get round by crawling on the seafloor. The headless hen monster, nonetheless, is totally different as it could actually swim for much longer distances by pulsing its fin-like ‘flaps’.
“I really like sea cucumbers,” says Guadalupe ‘Lupita’ Bribiesca-Contreras, an utilized scientist on the Nationwide Oceanography Centre in Southampton, within the footage. “In the event that they get upset, they’ll expel their entire intestine they usually nonetheless survive – they’ll regenerate the intestine.”
The footage was filmed in 2023, when filmmaker Eleanor Mortimer joined a gaggle of deep-sea scientists on their analysis vessel. They had been studying the Clarion-Clipperton Zone, which is without doubt one of the most distant areas on Earth. It takes round 12 days to succeed in from the closest fringe of land.
This huge abyssal plain is within the Pacific Ocean between Hawaii and Mexico and covers 4.5 million sq. kilometres (1.7 million sq. miles). It has a mean depth of 5,000 metres. Whereas it’s thought to comprise extraordinary biodiversity, little is understood about it.
Into the deep
To handle this, London’s Pure Historical past Museum is finishing up analysis on this zone, led by its Deep Sea Lab Group. The Clarion-Clipperton Zone additionally comprises polymetallic nodules, that are potato-sized lumps of rock. These rocks comprise giant portions of metals, which can be crucial for future inexperienced know-how akin to producing electrical automobile batteries.
Whereas no deep-sea mining is presently allowed within the Clarion-Clipperton Zone, the Worldwide Seabed Authority has issued licences to polymetallic nodule contractors for its exploration. Some researchers are involved in regards to the potential impression on the creatures that dwell there – lots of them presently unknown to science.
Mortimer’s ensuing documentary – How Deep Is Your Love – explores simply a few of this analysis, following the worldwide crew of scientists as they observe what’s down beneath.
“From the second I began enthusiastic about this movie I all the time imagined the animals’ perspective on our varied makes an attempt to discover their world – what would a remotely operated automobile from a science ship seem like for animals used to perpetual darkness for hundreds of years?” explains Mortimer.
“I made a decision to make use of the imaginative house of the movie to carry the deep-sea animals into the human panorama, an inverse of the human exploration of the deep.”
Screenings of the film are happening across the UK from September 2026.
