Exudates are substances produced by plants which do not contain living cells; they include nectar, sap, gum, latex, and resin. Exudates vary considerably in their biochemical composition, their function, and the frequency and quantity with which they are produced. Primates can consume nectar, sap, and latex; however, most primates consume gums. Primates of the Callitrichinae, Galaginae, and Cheirogaleidae show the greatest anatomical specializations for exudate foraging and digestion. Adaptations for exudativory include chisel‐like incisors for scraping and gouging, claw‐like nails for clinging to tree trunks, and enlarged cecums where microbes ferment gums into digestible molecules. Unlike other plant foods, many exudates are available year‐round: likely as a result of this benefit, exudativory has evolved numerous times in a variety of primate taxonomic groups.
