Under the Antarctic Ice--Antarctic Toothfish
Swimming beneath the Antarctic ice, an Antarctic toothfish (Dissostichus mawsoni) is photographed by "seal cam." Seal cam is an on-going National Science Foundation (NSF)-supported project where scientists use seals as "eyes" to see what goes on underneath the Antarctic ice. Antarctic Weddell seals are a predator of the toothfish.
Toothfish are found throughout Antarctica and the Antarctic Peninsula, South Orkney Islands and South Shetland Islands, from 0 to 695 meters depth. Toothfish are commonly seen with the sea ice along the Antarctic shore and have been observed clinging to the underside of thick ice shelves. The toothfish can grow up to 28 centimeters in length. A well-adapted hunter, the lateral line sensory system of the toothfish can detect prey by recognizing the low vibration frequencies emitted by swimming crustaceans. Toothfish eat free-swimming, shelled pteropod mollusk, ice krill, copepods, decapod crustacean larvae, chaetognaths, amphipods and juvenile fish. [Image 7 of 7 related images.
