Boobies received their name by allowing them to be captured while asleep. Boobies are a part of the Sulidae family made up of ten species of long-winged sea birds the size of geese. Their feet are completely webbed including hind toes, not free as in a duck. Boobies live near tropical and subtropical islands around the world, coming ashore only to breed. At sea they can be seen diving from the sky to catch fish.
