Shark Bay, on the western tip of Australia, showcases natural beauty, diverse sea life and wide-ranging geography. It has the largest seagrass bed in the world, dozens of endemic animal species, five endangered mammal species and more than a third of Australia’s bird species. A distinguishing Shark Bay feature: the stromatolites, rock-like structures formed by blue-green algae colonies. Stromatolites are among the Earth’s oldest life forms, originating on the planet 3.5 billion years ago. Shark Bay’s stromatolites are similar to their ancient ancestors, serving as a window into life early in the Earth’s history.
