鸭子的英文简介如题,不需太长

Duck is the common name for a number of species in the Anatidae family of birds.The ducks are divided between several subfamilies in the Anatidae family; they do not represent a monophyletic group but a form taxon,since swans and geese are not considered ducks.Ducks are mostly aquatic birds,mostly smaller than the swans and geese,and may be found in both fresh water and sea water.
