These Islands are the home of a vast colony of sea birds, such as the true pirate of the sky, the magnificent frigate bird, egrets, herons, sea gulls, pelicans, brown boobies and the world famous galapagos Blue-footed Booby. Different species of corals inhabit these areas and of course, many different species of fish enjoy the safety and productivity of the surrounding waters. You might spot King Angelfish, Panamic Sergeant Majors, Cortez Chubs, Giant Damselfish, Moorish Idol, Rainbow Wrasse, and many more.
