Surviving in the Ross seaEmperor penguins and Weddell seals ar the only marine predators that breath air and live year one shot in Antarctica Ross Sea. How these ii animals are able to live among each opposite when there fodders, hunting perspicacitys and area distribution are shared is the question. Ross Sea is called home by six emperor penguin colonies, approximately 180,000 birds, and about 50,000 Weddell seals. It is important, when considering aspiration between these two species to know that each share above and on a lower floor water resources however it is below water target where problems may occur. some(prenominal) items can be considered to determine true competition overlap. These items include prey selection, using various hunting depths and habitat separation.Fish account for close of the diet of both predators (99.3 % for seals and 89-95% for penguins). To take it one step further, Pleuragramma antarcticum, or Antarctica silverfish is the primary prey for each. Of the fish consumed, 88.6% of penguins fish diet and 99.3% of the seals diet consist of the Antarctic silverfish. This species of penguins and seals do not select fish of different classes despite body and mouth size difference. Seal prey is somewhat large, yet still considered juvenile as are penguin prey. Absence of larger prey in the penguin diet may be due to the event that all samples were collected during chick rearing periods. It is possible that adult birds would fuck off larger fish for themselves and return with slightly smaller sizes for their young. Although seals and penguins hunt for the kindred size and species of fish, this does not restrict them from cohabitation.Next we will consider the depth at which they hunt. Both, seal and penguins are excellent absorbrs. In order to dive at great depths, these species move oxygen away from the lungs and into the muscles and blood. This allows them to store 3-4 generation more oxygen than the average land mammal . In addition, seals and penguins use another(prenominal) techniques to reduce oxygen intake. Examples of this include the reduction of heart rates during coarse dives and an energy conserving swim pattern called burst and glide. It is known that penguins and seals have the mightiness to reach similar depths, however, the time below surface varies between the two animals.
