Penguin – Natural Threats
The main threats for penguins in water are leopard seals, fur seals, sea lions, sharks and killer whales. On land, foxes, snakes, lizards, dogs and some other animals are a threat for eggs and chicks in the case of species not in the Antarctic regions, like the Galapagos penguin among others. For those living in Antarctic regions, the main threats on land are predatory birds like petrels and skuas.
Seagulls and ibises threaten African penguins on land.
