Cayman vents are world's hottest (BBC) {450 C black smokers}
By Matt McGrath
Science reporter, BBC World Service
The world's deepest known volcanic vents are also the hottest, a UK-led expedition has indicated.
The seafloor vents are located 5km below the surface of the Caribbean, in the Cayman Trough.
The researchers say the structures are shooting jets of mineral-rich water more than a kilometre into the ocean above.
The vents' features suggest the water is warmer than 450C - hot enough to melt lead.
Nevertheless, the springs are teeming with new species including a type of pale shrimp with a light sensing organ on its back.
