Summary
Abstract: Antarctic krill (Euphausia superba) are found throughout much of their life in schools. In the laboratory however, this fundamental behaviour has been observed only on one occasion in the last twenty five years and until now subsequent attempts to induce krill to school in the laboratory have failed. Here we present new observations of schooling and swarming behaviour by Antarctic krill in the laboratory at the Australian Antarctic Division in Kingston, Tasmania. We describe the typical aggregations observed and the responses of the aggregations to a variety of stimuli. Additionally we present the results of a pilot study to make quantitative observations of individual krill within a school using three dimensional motion analysis.
