Abstract
    A hyperbenthic baited trap was deployed at three sites in Lützow-Holm Bay and off Enderby Land, Antarctica, in the 1993/1994 summer to investigate the species composition, distribution, and abundance of necrophagous animals. The trap consisted of four chambers, with a length of 100 cm and a diameter of 38 cm. The sample at the abyssal site, 3,186 m deep, contained 74 individuals of 6 species, completely different from that at the other 2 sites on the continental shelf; it was dominated by the large amphipod Eurythenes gryllus, a cosmopolitan species recorded from bathyal to abyssal depths. The species composition of the continental shelf sites, 93-137 individuals of 10-12 species, was dominated by species endemic to Antarctica, such as the small amphipod Pseudorchomene coatsi and the isopod Natatolana meridionalis; in these continental shelf sites, a high degree of species diversity was observed.
