Ovophagy is a rare though widely observed condition in the reproduction Reproduction is the biological process by which new individual organisms are produced. Reproduction is a fundamental feature of all known life; each individual organism exists as the result of reproduction. The known methods of reproduction are broadly grouped into two main types: sexual and asexual of certain animals Animals are a major group of mostly multicellular, eukaryotic organisms of the kingdom Animalia or Metazoa. Their body plan eventually becomes fixed as they develop, although some undergo a process of metamorphosis later on in their life. Most animals are motile, meaning they can move spontaneously and independently. All animals are also, whereby fetuses A fetus is a developing mammal or other viviparous vertebrate after the embryonic stage and before birth. The plural is fetuses will devour each other prior to birth Birth is the act or process of bearing or bringing forth offspring . The offspring is brought forth from the mother. Different forms of birth are oviparity, vivipary or ovovivipary. Subsequent research has shown ovophagy to be sporadic and highly uncommon among the vast majority of animal species.

Ovophagy is morphologically not possible among human Humans commonly refers to the species Homo sapiens , the only extant member of the Homo genus of bipedal primates in Hominidae, the great ape family. However, in some cases the term is used to refer to any member of the genus Homo fetuses; that is, it is physically impossible for one human fetus to devour or otherwise "consume" a sibling.

Feeding behaviours Feeding is the process by which organisms, typically animals, obtain food. Terminology often uses either the suffix -vore from Latin vorare, meaning 'to devour', or phagy, from Greek φαγειν, meaning 'to eat'
Carnivores A carnivore , meaning 'meat eater' (Latin carne meaning 'flesh' and vorare meaning 'to devour'), is an organism that derives its energy and nutrient requirements from a diet consisting mainly or exclusively of animal tissue, whether through predation or scavenging. Animals that depend solely on animal flesh for their nutrient requirements are
adult Hematophagy Hematophagy is the habit of certain animals of feeding on blood (from the Greek words, haima "blood" and phagein "to eat"). Since blood is a fluid tissue rich in nutritious proteins and lipids that can be taken without enormous effort, hematophagy has evolved as a preferred form of feeding in many small animals such as worms · Insectivore Although individually small, insects exist in enormous numbers and make up a very large part of the animal biomass in almost all non-marine environments. In Queensland pastures, for example, it is normal to have a greater total weight of Scarabaeidae larvae under the surface than of the beef cattle grazing above it · Lepidophagy Lepidophagy is a specialised feeding behaviour in fish that involves eating of scales of other fish. Lepidophagy is widespread, having been independently evolved in at least five freshwater families and seven marine families. Lepidophagy has been reported in a range of fish including: Chanda nama , Terapon jarbua (family Terapontidae), several · Man-eater Man-eater is a colloquial term for an animal that preys upon humans. This does not include scavenging. Although human beings can be attacked by many kinds of animals, man-eaters are those that have incorporated human flesh into their usual diet. Most reported cases of man-eaters have involved tigers, leopards, lions, crocodilians, and sharks · Molluscivore A molluscivore is a carnivorous animal which eats mainly molluscs. The term durophagy is used to describe this eating behavior · Mucophagy Mucophagy is feeding on mucus of fishes or invertebrates. It may also refer to consumption of mucus or dried mucus in primates · Myrmecophagy Myrmecophagy is a feeding behavior defined by the consumption of termites and/or ants, particularly in those animal species whose diets are largely or exclusively composed of said insect types · Ophiophagy Ophiophagy is a specialized form of feeding or alimentary behavior of animals which hunt and eat snakes. There are ophiophagous mammals (such as the skunks and the mongooses), birds (such as snake eagles, the Secretary Bird, and some hawks), lizards (such as the Common collared lizard), and even other snakes, such as the Central and South American · Piscivore Some animals, like the sea lion, or alligator, are not completely piscivorous, while others, like the Aquatic Genet, are strictly dependent on fish for food. The name piscivore is derived from the Latin word for fish, "piscis" · Spongivore A spongivore is an organism that feeds primarily on animals of the Phylum Porifera, commonly called sea sponges
reproductive Oophagy Oophagy , literally "egg eating", is the practice of embryos feeding on eggs produced by the ovary while still inside the mother's uterus. The word oophagy is formed from the Classical Greek ᾠόν (ōion, egg) and Classical Greek φᾱγεῖν (phāgein, to eat) · Ovophagy · Paedophagy Paedophagy literally means the "consumption of children". It is a term used to describe the feeding behaviour of fish, or other animals, whose diet is partially, or primarily the eggs or larvae of other animals. The term is frequently applied to various species of cichlid fish from Lake Malawi of the genera Caprichromis, · Placentophagy Placentophagy is the act of mammals eating the placenta of their young after childbirth · Breastfeeding Breastfeeding is the feeding of an infant or young child with breast milk directly from female human breasts rather than from a baby bottle or other container. Babies have a sucking reflex that enables them to suck and swallow milk. Most mothers can breastfeed for six months or more, without the addition of infant formula or solid food · Weaning Weaning is the process of gradually introducing a mammal infant, either human or animal, to what will be its adult diet and withdrawing the supply of its mother's milk
cannibalistic Cannibalism In zoology, cannibalism is the act of one individual of a species consuming all or part of another individual of the same species as food. Cannibalism is a common ecological interaction in the animal kingdom and has been recorded for more than 1500 species[citation needed] · Human cannibalism Cannibalism , also called anthropophagy, is the act or practice of humans eating the flesh of other human beings · Self-cannibalism Self-cannibalism is the practice of eating oneself, also called autocannibalism, or autosarcophagy. A similar term which is applied differently is autophagy, which specifically denotes the normal process of self-degradation by cells. While almost an exclusive term for this process, autophagy nonetheless has occasionally made its way into more · Sexual cannibalism
Herbivores Herbivory is a form of predation in which an organism consumes principally autotrophs such as plants, algae and photosynthesizing bacteria. By that definition, many fungi, some bacteria, many animals, some protists and a small number of parasitic plants can be considered herbivores. However, herbivory is generally restricted to animals eating Folivore In zoology, a folivore is a herbivore that specializes in eating leaves. Mature leaves contain a high proportion of hard-to-digest cellulose, relatively little energy, and often toxic compounds.. For this reason folivorous animals tend to have long digestive tracts and slow metabolisms. Many enlist the help of symbiotic bacteria to release the · Frugivore A frugivore is a fruit eater. It can be any type of herbivore, omnivore or carnivore where fruit is a preferred food type. Frugivory is a very common diet choice. For example, 20% of herbivorous mammals could be sub-classed as frugivore/herbivore if such a classification existed in science. Since frugivorous/herbivores eat a lot of fruit they are · Graminivore In zoology, a graminivore is an herbivorous animal that feeds primarily on grass (specifically "true" grasses; plants of the family Poaceae). The word is derived from Latin graminis, meaning "grass", and vorare, meaning "to eat." Graminivory is a form of grazing · Granivore Seed predation, often referred to as granivory, is a type of plant-animal interaction in which granivores feed on the seeds of plants as a main or exclusive food source (Hulme and Benkman 2002), in many cases leaving the seeds damaged and not viable. Granivores are found across many families of vertebrates and invertebrates (especially mammals, · Nectarivore In zoology, nectarivore is an animal which eats the sugar-rich nectar produced by flowering plants. Most nectarivores are insects or birds, but there are also nectarivorous mammals, notably several species of bats in the Southwestern United States and Mexico, as well as the Australian Honey Possum , and Geckos (genus Phesulma) in Mauritius. The · Palynivore In zoology, a palynivore is an herbivorous animal which selectively eats the nutrient-rich pollen produced by angiosperms and gymnosperms. Most true palynivores are insects or mites. The category in its strictest application includes essentially all bees, and a few different kinds of wasps, as pollen is often the only solid food consumed by all · Xylophagy Xylophagy is a term used in ecology to describe the habits of an herbivorous animal whose diet consists primarily of wood. The word derives from Greek ξυλοφάγος (xulophagos) "eating wood", from ξύλον (xulon) "wood" and φαγεῖν (phagein) "to eat", an ancient Greek name for a kind of a worm-eating · Osteophagy Osteophagy is the practice whereby herbivores consume bones. This practice usually occurs place in a nutrient-deficient environment. The animals consume the bones in order to obtain such necessary elements as phosphorus and calcium
Others Phagocytosis Phagocytosis [from Greek , phago- "eating", -cyte "vessel", -osis a process] is the cellular process of phagocytes and protists of engulfing solid particles by the cell membrane to form an internal phagosome. Phagocytosis is a specific form of endocytosis involving the vesicular internalization of solid particles, such as · Bacterivore Bacterivores are free-living, generally heterotrophic organisms, exclusively microscopic, which obtain energy and nutrients primarily or entirely from the consumption of bacteria. Many species of amoeba are bacterivores, as well as other types of protozoans. In common all species of bacteria will be prey. But spores of some species like · Coprophagia Coprophagia is the feasting upon feces, from the Greek κόπρος copros and φαγεῖν phagein ("to eat"). Many animal species practice coprophagia as a matter of course; other species do not normally feast upon feces but may do so under unusual conditions · Detritivore Detritivores, also known as detritus feeders or saprophages, are heterotrophs that obtain nutrients by consuming detritus . By doing so, they contribute to decomposition and the nutrient cycles · Fungivore A fungivore or mycophage is any animal that primarily or solely feeds upon living members of the fungus kingdom. Fungivory is a type of predation, and is an important part of the soil food web. However, some animals that are quite strictly herbivorous, such as wombats, will consume fungi if they are available · Geophagy Geophagy is the practice of eating earthy or soil-like substances such as clay, and chalk, in order to obtain essential nutrients such as sulfur and phosphorus from the soil. This practice is widespread among animals in the wild, as well as in human societies. Human geophagy is closely related to pica, a classified eating disorder in the DSM-IV · Omnivore Omnivores (from Latin: omni all, everything; vorare to devour) are species that eat both plants and animals as their primary food source. They are opportunistic, general feeders not specifically adapted to eat and digest either meat or plant material exclusively. Pigs are one well-known example of an omnivore. Crows are another example of an
Methods Apex predator Apex predators are predators that have virtually no predators of their own, residing at the top of their food chain. Apex predator species are often at the end of long food chains, where they have a crucial role in maintaining the health of ecosystems · Bottom feeding A bottom feeder is an aquatic animal that feeds on or near the bottom of a body of water. The body of water could be the ocean, a lake, a river, or an aquarium. "Bottom feeder" is a general term which is used particularly in the context of aquariums. More specific terms for bottom feeders are: groundfish, demersal fish and benthos · Browsing Browsing is a type of predation in which a herbivore feeds on leaves, soft shoots, or fruits of high growing, generally woody, plants such as shrubs. This is contrasted with grazing predation, usually associated with animals feeding on grass or other low vegetation. An example of this dichotomy are goats (which are browsers) and sheep (which are · Hypercarnivore A hypercarnivore is an animal where more than 70% of the diet is meat from vertebrate animals, with the balance consisting of nonvertebrate foods which may include fungi, fruits and other plant material. Some examples include dolphins, eagles, snakes, marlin, most sharks, and such invertebrates as octopuses and sea stars. Additionally, this term · Filter feeding Filter feeders are animals that feed by straining suspended matter and food particles from water, typically by passing the water over a specialized filtering structure. Some animals that use this method of feeding are clams, krill, sponges, some fish and sharks, and baleen whales. Some birds, such as flamingos, are also filter feeders. Filter · Grazing Grazing generally describes a type of predation in which a herbivore feeds on plants , and also on other multicellular autotrophs (such as algae). Grazing differs from true predation because the organism being eaten is not killed, and it differs from parasitism as the two organisms do not live together, nor is the grazer necessarily so limited in · Kleptoparasitism Kleptoparasitism or cleptoparasitism is a form of feeding in which one animal takes prey or other food from another that has caught, collected, or otherwise prepared the food, including stored food (as in the case of cuckoo bees, which lay their eggs on the pollen masses made by other bees). The term is also used to describe the stealing of nest · Scavenging Scavenging, or necrophagy, is a carnivorous feeding behaviour in which a predator consumes corpses or carrion that were not killed to be eaten by the predator or others of its species. Scavengers play an important role in the ecosystem by contributing to the decomposition of dead animal remains. Decomposers complete this process, by consuming the · Trophallaxis Trophallaxis is the transfer of food or other fluids among members of a community through mouth-to-mouth or anus-to-mouth (proctodeal) feeding. It is most highly developed in social insects such as ants, termites, wasps and bees. The word was introduced by the entomologist William Morton Wheeler in 1918. The behaviour was used in the past to
