Scientists have found the first multicellular animals that apparently live entirely without oxygen. The creatures reside deep in one of the harshest environments on earth: the Mediterranean Ocean's L'Atalante basin, which contains salt brine so dense that it doesn't mix with the oxygen-containing waters above. Previous samples taken from the water and sediments in the basin showed that single-celled life was present, but a new study published this week in BMC Biology has identified multi-cellular animals that apparently live and reproduce in the sediments under the salt brine. Italian and Danish researchers describe three new species of tiny animals called Loricifera.
