Paedophagy (literally meaning the "consumption of children") in its general form is the feeding behaviour of fish or other animals whose diet is partially, or primarily the eggs or larvae of other animals. However, P. H. Greenwood, who was the first to describe paedophagia, defines it to be a feeding behaviour evolved among cichlid fishes.

Trophallaxis is a form of social feeding in many insects that contributes to the formation of social bonds. [5] Trophallaxis serves as a means of communication, at least in bees, like M. genalis, [16] and ants. [17] Trophallaxis in M. genalis is part of a social exchange system, where dominant bees are usually the recipients of food. [16]
Egg predation or ovivory is a feeding strategy in many groups of animals (ovivores) in which they consume eggs. Since a fertilized egg represents a complete organism at one stage of its life cycle , eating an egg is a form of predation , the killing of another organism for food.
The authors term their approach to feeding "parent-directed feeding", or PDF: [9] "Our conviction is that a baby should be fed when he or she signals readiness. With PDF, a mother feeds her baby when the baby is hungry, but she takes advantage of the first few weeks of life to guide the baby’s hunger patterns by a basic routine.
The linkages in a food web illustrate the feeding pathways, such as where heterotrophs obtain organic matter by feeding on autotrophs and other heterotrophs. The food web is a simplified illustration of the various methods of feeding that link an ecosystem into a unified system of exchange.
Oophagy (/ oʊ ˈ ɒ f ə dʒ i / oh-OFF-ə-jee) or ovophagy, literally "egg eating", is the practice of embryos feeding on eggs produced by the ovary while still inside the mother's uterus. [1] The word oophagy is formed from the classical Greek ᾠόν ( ōion , "egg") and classical Greek φᾱγεῖν ( phāgein , "to eat").
