In zoology Zoology, also spelled zoölogy, is the branch of biology that focuses on the structure, function, behavior, and evolution of animals. The zoologist's pronunciation of "zoology" is /zoʊˈɑlədʒɪ/, though a common spelling pronunciation is /zuːˈɑlədʒɪ/, a palynivore is an herbivorous Herbivory is a form of predation in which an organism, known as a herbivore, 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 animal which selectively eats the nutrient-rich pollen Pollen is a fine to coarse powder consisting of microgametophytes , which produce the male gametes (sperm cells) of seed plants. A hard coat covering the pollen grain protects the sperm cells during the process of their movement between the stamens of the flower to the pistil of the next flower. Individual pollen grains are small enough to require produced by angiosperms The flowering plants or angiosperms are the most diverse group of land plants. The flowering plants and the gymnosperms are the only extant groups of seed plants. The flowering plants are distinguished from other seed plants by a series of apomorphies, or derived characteristics and gymnosperms Gymnosperm is a group of spermatophyte seed-bearing plants with ovules on scales, which are usually arranged in cone-like structures. Most true palynivores are insects Insects are arthropods, having a hard exoskeleton, a three-part body (head, thorax, and abdomen), three pairs of jointed legs, compound eyes, and two antennae. They are the most diverse group of animals on the planet and include approximately 30 Notoptera, 35 Zoraptera, 150 snakefly, 200 silverfish, 300 alderfly, 300 webspinner, 350 jumping or mites Mites, along with ticks, belong to the subclass Acarina and the class Arachnida. Mites are among the most diverse and successful of all the invertebrate groups. They have exploited an incredible array of habitats, and because of their small size (most are microscopic) most go totally unnoticed. Many live freely in the soil or water, but there are. The category in its strictest application includes essentially all bees Bees are flying insects closely related to wasps and ants, and are known for their role in pollination and for producing honey and beeswax. Bees are a monophyletic lineage within the superfamily Apoidea, presently classified by the unranked taxon name Anthophila. There are nearly 20,000 known species of bees in nine recognized families, though, and a few different kinds of wasps A wasp is a predatory, flying, stinging insect, with a stinger and membranous forewings and hindwings. It is related to ants and bees, with all of them being members of order Hymenoptera, but is separated from ants and bees by having a stinger and no hair; bees have hair. A rough definition of the term wasp is any member of the aculeate family, as pollen is often the only solid food consumed by all life stages in these insects (palynivorous mites and thrips typically feed on the liquid content of the pollen grains without actually consuming the exine Pollen is a fine to coarse powder consisting of microgametophytes , which produce the male gametes (sperm cells) of seed plants. A hard coat covering the pollen grain protects the sperm cells during the process of their movement between the stamens of the flower to the pistil of the next flower). The list is expanded greatly if one takes into consideration species where either the larval or adult stage feeds on pollen, but not both; there are other wasps A wasp is a predatory, flying, stinging insect, with a stinger and membranous forewings and hindwings. It is related to ants and bees, with all of them being members of order Hymenoptera, but is separated from ants and bees by having a stinger and no hair; bees have hair. A rough definition of the term wasp is any member of the aculeate family which are in this category, as well as many beetles Beetles are the group of insects with the largest number of known species. They are classified in the order Coleoptera , which contains more described species than in any other order in the animal kingdom, constituting about 25% of all known life-forms. 40% of all described insect species are beetles (about 350,000 species), and new species are, flies True flies are insects of the order Diptera , possessing a single pair of wings on the mesothorax and a pair of halteres, derived from the hind wings, on the metathorax, butterflies A butterfly is an insect of the order Lepidoptera. Like all Lepidoptera, butterflies are notable for their unusual life cycle with a larval caterpillar stage, an inactive pupal stage, and a spectacular metamorphosis into a familiar and colourful winged adult form. Most species are day-flying so they regularly attract attention. The diverse, and moths A moth is an insect closely related to the butterfly, both being of the order Lepidoptera. The differences between butterflies and moths are more than just taxonomy. Sometimes the names "Rhopalocera" and "Heterocera" (moths) are used to formalize the popular distinction. Many attempts have been made to subdivide the Lepidoptera. There is a vast array of different insects that will feed opportunistically on pollen, as will various birds and other nectarivores In zoology, a 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.

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 adds humans to its diet. 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 wolves, tigers, leopards, lions, crocodiles, alligators, and sharks. However, they · 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, which serves no nutritional function · Myrmecophagy · 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 Crotaphytus collaris), and even other snakes, such as the Central and South American · Piscivore Some animals, like the sea lion, or alligator, are not completely piscivores, 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

Oophagy Oophagy is the practice of embryos feeding on eggs produced by the ovary while still inside the mother's uterus · Ovophagy Ovophagy is a rare though widely observed condition in the reproduction of certain animals, whereby fetuses will devour each other prior to birth. Subsequent research has shown ovophagy to be sporadic and highly uncommon among the vast majority of animal species · 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 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

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 is the act or practice of humans eating the flesh of other humans · 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. Whilst almost an exclusive term for this process, autophagy nonetheless has occasionally made its way into more · Sexual cannibalism

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, a 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 · 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" + φάγειν (phagein) "to eat" and it was an ancient Greek name for a kind of a worm · 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

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 consumption of 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 consume 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 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 omnivore that many people see every day. Humans are
