anas

Anas is a genus of ducks in the family Anatidae, within the order Anseriformes. Ducks assigned to Anas are commonly referred to as dabbling ducks, feeding mainly at the water's surface rather than diving. They are found in wetlands and open water across many continents, with diverse plumages and vocalizations. Members of Anas typically have broad bills and legs set toward the rear of the body, adaptations suited to surface feeding and wading.

Taxonomic classification of Anas has varied over time as molecular studies clarified relationships among dabbling ducks. Some species previously placed in Anas have been moved to other genera, such as Mareca and Spatula, leading to different circumscriptions among authorities. The genus historically included the mallard (Anas platyrhynchos) and several related forms; in many classifications the Mallard, domestic duck, and several other familiar and regional species are retained in Anas or adjacent groups. The exact composition of Anas thus depends on the taxonomic framework used by a given authority.

Anas is also a given name, of Arabic origin, used in various countries. It means sociability or companionship. Notable individuals with the name include Anas bin Malik, a companion of the Prophet Muhammad, who is cited in Islamic tradition. The name appears in different transliterations and can be found among speakers of different languages and cultures.
