an armadillo, literally a turtle-rabbit (see attestations)
See an image that represents ayotochtli in the Visual Lexicon of Aztec Hieroglyphs, ed. Stephanie Wood (Eugene, Ore.: Wired Humanities, 2020-present).
ayotochtli = stirring sticks; tortoise-shell cups (for chocolate)
"Although encased in horny plates, the flesh of the armadillo is very edible; hence, its Nahuatl name, ayotochtli, that combines turtle (ayot) with rabbit (tochtli)."
"ayotochtli s. Cuadrúpedo; especie de lagarto cubierto de escamas (Clav.)."
