In fishes the gills are located in gill chambers at the rear of the mouth (pharynx). Water is taken in through the mouth, is forced through openings called gill slits, and then passes through the gill clefts, spaces between the ranks of delicate gills, bathing them continuously.n the process of animal evolution, gills first appear in annelid worms, in the form of simple, pectinate, or bipinnate plates and simple or branched filaments. They are located on the lateral motor appendages (in freely moving forms) or at the head end of the body (in those living in tubes).
