A new species of shrimp has been discovered living deeper than any seen before in the world's most extreme deep sea volcanic vents, the Daily Mail reported.

British scientists made the discovery while on an expedition to explore boiling undersea springs - which may be hotter than 450C - on the Caribbean seafloor. Some 5,000 meters down, in a rift in the seafloor, exists a volcanic spring known as a 'black smoker', which fires a jet of mineral-laden water more than a kilometer into the ocean above.

But, despite the extreme conditions, the vents are teeming with thousands of a new species of shrimp that has a light-sensing organ on its back.
