pelagic fish near the shelf break, and have breeding colonies on the Neptune Islands and Liguanea Island. Australian sea lions (Neophoca cinerea) have breeding colonies on Little Waldegrave Island, Olive Island, Seal Bay on Kangaroo Island, and Dangerous Reef in Spencer Gulf. The seasonal upwelling of nutrient-rich water along the western Eyre Peninsula and at the Kangaroo Island Pool nurtures plankton, krill, and fish, which provide food for dolphins, Australian little penguins (Eudyptula novaehollandiae), and blue whales (Balaenoptera musculus).
