Distribution of carnivorous benthic invertebrate in the northeastern part of Lutzow-Holm Bay, Antarctica

Benthic invertebrates were collected by bait traps at 35 stations scattered in the northeastern part of Lutzow-Holm Bay from May to September 1980. A total of 1103 carnivorous benthic invertebrates was obtained. They consisted of 41 species belonging to eight classes. Ophionotus victoriae was collec...

Description
Summary:Benthic invertebrates were collected by bait traps at 35 stations scattered in the northeastern part of Lutzow-Holm Bay from May to September 1980. A total of 1103 carnivorous benthic invertebrates was obtained. They consisted of 41 species belonging to eight classes. Ophionotus victoriae was collected as many as 659 specimens occupying 59.7% of total invertebrates and Neobuccinum eatoni was the second in number. While, only one specimen was collected in 22 species out of 41 species. Species number tended to be larger in the shallow continental shelf than in the deep glacial trough. Species number was also large in the northern part of the study area compared with the southern part. The relation between the distribution of invertebrates and the bottom topography in a small area was studied in the Kita-no-ura Cove.
