A team of British scientists has captured images of very rare species, in some of the most inaccessible parts of the Indian Ocean.

While they were surveying volcanic underwater vents, they found an array of creatures, including yeti crabs, scaly-foot snails and sea cucumbers.

They believe some of the species may be new to science.
