An obscure or archaic zoological term possibly referring to a type of waterfowl, duck, or duck-related organism, now largely obsolete.
Possibly derived from Latin anas 'duck' combined with other root elements, following older taxonomic naming conventions. Most such combined forms from early zoology have been replaced.
Old scientific names show how taxonomy was messier before DNA—scientists gave animals multiple names based on appearance, and many beautiful terms simply vanished as science modernized.
