A taxonomic group or infraorder containing sturgeons and closely related fish forms, emphasizing their evolutionary relationships.
From acipenseroid plus the Latin masculine plural ending -ei, used in higher taxonomic ranks to group related families and genera together.
These nested Latin endings are like Russian nesting dolls—each suffix adds another layer of biological relationship, zooming out from species to family to infraorder.
