The Falkland Islands wolf, or warrah, may have been the world’s loneliest land mammal. It was marooned for thousands of years on the wind-swept Falkland Islands with only seabirds, penguins and seals for company. They lived on both the east and west sides of the islands. They inhabit rocky mountainous terrain or boggy plains and beaches. They were reportedly seen swimming while foraging along the beaches.
