    Spatial distribution patterns of elasipod holothurians from the southern Weddell Sea were studied by analysing underwater photographs and trawl-catch data from 7 stations, ranging in depth from 240 to 1200 m. The 3 investigated species (Elpidia glacialis, Achlyonice violaecuspidata, Scotoplanes globosa) occurred in dense aggregations of differing spatial scale. For the first 2 species, median photographically determined densities within the patches were 17 and 6 ind. m-2 respectively. The size frequency distributions of all species were relatively broad. A behavioural communication between individuals assuring the formation and persistence of these aggregations is proposed.
