It is a low volcano barely breaking the surface of the ocean. Ships sail directly into its large crater to anchor at the foot of the steep walls. It attracts many seabirds, like frigate birds, red-footed and masked boobies, swallow-tailed gulls and storm petrels. They all breed here by the thousands. You can also find sea lions, white-cheeked pintail ducks, and Galapagos doves. Behind the small beach are a number of small tide pools, where lava gulls and yellow-crowned night herons are seen.
