The greatest depth at which plant life has been found is 295 m (968 ft) for an unidentified species of crustose coralline algae documented by Mark and Diane Littler (both USA) of the Smithsonian Institution on a seamount off San Salvador, Bahamas, in October 1984.
These maroon-coloured plants survived although 99.9995 per cent of sunlight was filtered out at their location on the seabed.
