The family Anatidae comprises seven subfamilies, including Anatinae. The subfamily Anatinae was first described by William Elford Leach, MD, FRS (2 February 1791 – 25 August 1836), an English zoologist and marine biologist, in the year 1820.

Several genera have been placed under the subfamily Anatinae, including Anas. The genus Anas was first described by Carl Linnaeus (23 May 1707 – 10 January 1778), a Swedish botanist, physician and zoologist, in the year 1758.
