ABSTRACT
ABSTRACT: Biodiversity surveys of Australia’s little sampled western and south-eastern continental margins in 2005 and 2007 found that echinoderms are a major component of deep invertebrate megafaunas. Species-level determinations made by experts from Australian and international institutions showed these collections contained many new species and/or new species records for Australia, particularly of asteroids and crinoids-the deep-sea elements of which are less studied than other echinoderm groups. High resolution video and still images, and multi-beam sonar data, were collected at the same locations and permit faunal distributions and habitat associations to be evaluated.
