Rockhopper penguins live in steep, rocky places. The only way they can get around on land is to hop from rock to rock. Rockhoppers grow about 46 cm tall - almost as high as an adult's knee. They are the smallest of the crested penguins. They are carnivores that eat sea animals such as fishes, krill, and squid.
