#cayman trough

Scientists working at the deep sea trench known as the Cayman Trough (near the Cayman islands in the Caribbean) have recently discovered a new group of vents which reading show are the deepest (at 4,968 metres - approximately 3 miles) and hottest (401 degrees celcius) to be found yet. The scientists are hoping the research they are conducting in this mysterious black-water-belching murkiness can help us better understand exactly how, and why life has come to exist in such extremely hostile environments.
