Gentoos live as far south as the bare icy shores of Antarctica and as far north as the grassy meadows of islands off South America. The colder-climate gentoos have smaller wings, feet and beaks -- a way to conserve heat.
Like all penguins, Gentoos have dense bones compared to birds that can fly. Actually, penguins evolved from "flighted" birds over 60 million years ago. Their flippers are really wings that have been modified for "flying" underwater. These "flights" can take them 350 feet deep to search for krill, fish and squid. Penguins have the largest number of feathers per square inch of any birds.
