Trophallaxis () is the direct transfer of fluid and food (excreted, secreted or regurgitated) between individuals, typically through mouth-to-mouth (stomodeal) or anus-to-mouth (proctodeal) feeding. Along with nutrients, trophallaxis can involve the transfer of molecules such as proteins, hormones, organisms such as symbionts, and information to serve as a form of communication.
