 Their food consists of fishes, crabs, and other marine animals, which

 year, for the purpose of breeding. 

 They are incapable of flight, and move in water by diving and swim-

 (see seal), while the feathers, which lie close against the body, are well 

 soaked in oil (see duck). In some species the feathers of the back and 

 of the upper surface of the wings even assume the form of scales.
