Description:
The hunting behavior of a marine mammal was studied beneath the Antarctic fast ice with an animal-borne video system and data recorder. Weddell seals stalked large Antarctic cod and the smaller subice fish Pagothenia borchgrevinki, often with the under-ice surface for backlighting, which implies that vision is important for hunting. They approached to within centimeters of cod without startling the fish. Seals flushed P. borchgrevinki by blowing air into subice crevices or pursued them into the platelet ice. These observations highlight the broad range of insights that are possible with simultaneous recordings of video, audio, three-dimensional dive paths, and locomotor effort.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Davis -- Fuiman -- Williams -- Collier -- Hagey -- Kanatous -- Kohin -- Horning -- New York, N.Y. -- Science. 1999 Feb 12;283(5404):993-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Marine Biology, Texas A&M University, 5007 Avenue U, Galveston, TX 77553, USA.
