Kangaroo Island - Sea Lion 'seals' -- the seals look exhausted because every 3 days they have to swim out into the open ocean and hunt for food and stay awake day and night to avoid becoming prey themselves for whales or sharks. Mothers have to leave their pups on the beach and hope other aggressive seals do not hurt them. The small seals in the pictures are just such pups left on their own by their mothers out hunting for food.
