The stomach of a large dead great white shark found beached in Southeast Alaska contained undigested salmon parts, but large great white sharks tend to eat marine mammals because of their higher fat content. Great white shark predation in Alaskan waters may afford some stability to the ecosystem by removing and controlling other large marine predator. Great white shark predation may be limiting the predation by intermediate-sized predators. Great white shark predation on beluga whales in Cook Inlet may be pushing this population of white whales to the brink of extension. The complexities of the predator–prey relationship and their effects on the marine ecosystem are difficult and next-to-impossible to predict and manage.
