+name: guttural pouch
+def: "A paired ventral diverticulum of the auditory (pharyngotympanic) tube, formed by escape of the mucosal lining of the tube through a relatively long ventral slit in the supporting cartilages. The pouches are normally air filled and in the domestic horse can have a capacity of 300-500ml." [ISBN:978-0721649610, Wikipedia:Guttural_pouch]
+comment: The guttural pouch is present in members of the order Perissodactyla (nonruminant ungulates: horses, tapirs, rhinoceroses) and in a small group of other mammals including hyraxes, certain bats, and a South American mouse.
