A critical re-examination of the evidence for a possible dependence of Weddell seals (Leptonychotes weddellii) on Antarctic toothfish (Dissostichus mawsoni) in the Ross Sea, Antarctica
Weddell seals (Leptonychotes weddellii), but available evidence remains inconclusive as a result of both ... . As a new approach, we also estimate Weddell seal food requirements by considering nutritional quality ... energy requirements. The energy density of potential prey items (fish and invertebrates) covers a four ... -fold range. Nutritional analysis of Ross Sea prey suggests that toothfish may represent a unique high ...
