The modern domestic duck originates from the wild mallard. Believed to have been domesticated as many as 8,000 years ago, the duck has long served as a stable food source for humans. The duck’s beak, or bill, is designed for feeding on aquatic vegetation, macro-invertebrates, grains and the occasional vertebrate. This, coupled with its webbed feet, make the duck perfectly adapted to its aquatic habitat.nnSpecifications:nn1: 1 scalennPolyurethane resin castn1-part skull (jaw glued to cranium)nnSkull Length 14.1 cm (5.6 in.)nSkull Width 4.5 cm (1.8 in.)nSkull Height 5 cm (2 in.)nnOrigin: Worldwide
