the Anku (Delearus ploutonus) are a race of small, humanoid aliens living on Pluto. they, along with the Lungores and Xali, make up the bulk of intelligent life on the planetoid.

they are very distantly related to the Manbu (Delearus kythereus) on Venus.

they generally call themselves some variation of an-quu, meaning "common folk", however an-paa'lung "people of Paa'lung (Pluto)" and the dated kxii-qx̣ii (exact meaning unknown) are found as well.
