Guttural pouch

In the equids (horse family) and some species such as the desert hyrax, the guttural pouch is one of a pair of air chambers in the neck just behind the skull and below the ears. These pouches are on both sides of the head and are air-filled out-pouchings or evaginations to the Eustachian tube, leading into the nasopharynx.
