Great biodiversity is found thanks to the Humboldt current and the phenomenon of outcropping in addition to other factors such as the sun and winds. Birdwatchers will find a lot of these such as seagulls, seagulls, pikemen, cormorants, pelicans, vultures and Humboldt penguins. You will also see crustaceans, echinoderms, molluscs, seaweed and others. Definitely the highlight of the Tour to the Ballestas Islands are the sea lions or sea lions who steal everyone's attention for the curious ness of their behaviour (sleep, "pose for the cameras", or simply socialise and live without problems because they occupy the top of the food chain in the area without natural predators).
