Scientific name: Euphausia superba

Details: the grid of the 3nd degree setae in the gaps of the 2nd degree setae

Special: one of the most remarkable filters ever built on this planet to hunt for even the tinyest partticles and plankton-organisms (mesh-openings down to 2 micron) - in the winter this structure is capable of harvesting ice algae from under the icebergs with rake-like structures (at the very tip of the filtering-legs)

Status: Scan from a bad copy of the ICES contribution C. M. 1980 / L:54 with associated poster and high resolution images - Biological Oceanography Committee - ALBERTI, G., KILS, U.: The Filtering Basket of Euphausia superba Institut fuer Meereskunde - Original was found and better resolutions will be up soon on this server

Dynamic: The function of the filtering basket during pump filtering, tow filtering and ice scraping will be on videos on this server, an interactive CD under coonstruction
