Changing ocean patterns and weather conditions can cause changes in penguin's diets. Different species hunt in various ways and places. Some penguins prefer shallow water while others dive deep for their prey. Galapagos penguins usually do their hunting within a mile of their nest, whereas emperor penguins have been known to travel 500 miles or more to forage food for weeks at a time.
