Rockhopper penguins live up to their name as they navigate the rugged coastline of Marion Island, a South African Antarctic Territory in the Indian Ocean.
Among the most numerous of penguins, rockhoppers are nevertheless considered vulnerable, and their population is declining, probably as the result of a decreasing food supply. The birds spend five to six months at sea, coming to shore only to molt and breed. They are often found bounding, rather than waddling as other penguins do, and are capable of diving to depths of up to 100 meters in pursuit of fish, crustaceans, squid and krill.
