Species filmed at deep-sea volcanic vent
Remarkable images of life from one of the most inhospitable spots in the ocean have been captured by scientists.
Researchers have been surveying volcanic underwater vents - sometimes called black smokers - in the South West Indian Ridge in the Indian Ocean.
The UK team found an array of creatures living in the super-heated waters, including yeti crabs, scaly-foot snails and sea cucumbers.
They believe some of the species may be new to science.
