Query: Does the koala eat anything other than eucalyptus?
Koalas are herbivorous, and while most of their diet consists of eucalypt leaves, they can be found in trees of other genera, such as "Acacia", "Allocasuarina", "Callitris", "Leptospermum", and "Melaleuca". They are able to digest the toxins present in eucalyptus leaves due to their production of cytochrome P450, which breaks down these poisons in the liver. Though the foliage of over 600 species of "Eucalyptus" is available, the koala shows a strong preference for around 30. They tend to choose species that have a high protein content and low proportions of fibre and lignin. The most favoured species are "Eucalyptus microcorys", "E. tereticornis", and "E. camaldulensis", which, on average, make up more than 20% of their diet. Despite its reputation as a fussy eater, the koala is more generalist than some other marsupial species, such as the greater glider. Since eucalypt leaves have a high water content, the koala does not need to drink often; its daily water turnover rate ranges from 71 to 91 ml/kg of body weight. Although females can meet their water requirements from eating leaves, larger males require additional water found on the ground or in tree hollows. When feeding, a koala holds onto a branch with hindpaws and one forepaw while the other forepaw grasps foliage. Small koalas can move close to the end of a branch, but larger ones stay near the thicker bases. Koalas consume up to of leaves a day, spread over four to six feeding sessions. Despite their adaptations to a low-energy lifestyle, they have meagre fat reserves and need to feed often.
Their diet includes the fruit and seeds of local cactus plants, as well as beans of the mesquite plant. They do not only eat vegetation, and also consume insects, small rodents and carrion. They have a variety of predators including the bobcat, coyotes, as well as local snakes and domestic animals such as dogs and cats.
This rail forages in shallow water near cover and eats mainly aquatic insects and crustaceans. It forages by probing the mud while moving around in shallow water.
This subspecies eats geckos, house mice, birds, and marsupials, including the Tammar wallaby.
The young of brooding red-eared firetails, "Stagonopleura oculata", were taken from a nest being observed.
The yellow-billed oxpecker eats insects and ticks. Both the English and scientific names arise from this species' habit of perching on large wild and domesticated mammals such as cattle and eating arthropod parasites. It will also perch on antelopes such as wildebeest. In a day an adult will take more than 100 engorged female "Boophilus decoloratus" ticks or 13,000 larvae.
The elephants comprise three living species and are the largest living land animals.Sirenia is an order of fully aquatic, herbivorous mammals that inhabit rivers, estuaries, coastal marine waters, swamps, and marine wetlands. All four species are endangered.The treeshrews are small mammals native to the tropical forests of Southeast Asia. Although called treeshrews, they are not true shrews and are not all arboreal.The two species of colugos make up the order Dermoptera. They are arboreal gliding mammals found in Southeast Asia.The order Primates contains humans and their closest relatives: lemurs, lorisoids, monkeys, and apes.Rodents make up the largest order of mammals, with over 40 percent of mammalian species. They have two incisors in the upper and lower jaw which grow continually and must be keep short by gnawing. Most rodents are small though the capybara can weigh up to 45 kg (100 lb).
A herbivore, the royal antelope prefers small quantities of fresh foliage and shoots; fruits and fungi may be taken occasionally. Though the antelope is considered to be nocturnal, zoologist Jonathan Kingdon holds that feeding occurs throughout the day, though some foraging may also be observed at night. In comparison to Bates's pygmy antelope, the royal antelope has a longer muzzle, broader lips, a smaller mouth and smaller cheek muscles. These features do not allow complete digestion of lignified growth. Individuals may often move into new locations foraging for fresh growth.
These forest dwelling antelope feed selectively on plants or plant parts such as shoots, roots, leaves, and buds, but their diet is mainly made up of fruits. The yellow-backed duiker is more efficient at digesting poor quality food than most other duiker species. This allows them to eat large, low quality fruits. Their diet makes them very hard to keep in captivity as most domesticated fruits are not well suited to their low fiber requirements. They are considered concentrate selectors, meaning they eat "diets relatively low in fiber, have a well developed ability to forage selectively, a rumen bypass, a rapid passage and high fermentation rate for starch, and they frequently encounter toxins."
The Virginia rail probe with its bill in mud or shallow water, also picking up food by sight. It mainly eat insects and other aquatic invertebrates, like beetles, flies, dragonflies, crayfish, snails and earthworms. It can also eat aquatic animals like frogs, fish and some small snakes, as well as seeds. Animal preys constitute the biggest part of this bird's diet, but vegetation contributes to its diet in the fall and winter.
Immelmann remarked that the species' ability to negotiate the dense vegetation of its habitat was more adept than that of other Australian grassfinches. They move along branches by pivoting from "side to side in small hops in an arc-like pattern." Downward, the red-eared firetail moves quickly and acrobatically through the thick foliage.
This is a bird which breeds in sub-tropical semi-desert with a few trees, such as acacia. It winters in open woodland or grassland. As the name suggests, bee-eaters predominantly eat insects, especially bees, wasps and hornets, which are caught in the air by sorties from an open perch. However, this species probably takes more dragonflies than any other food item. Its preferred hunting perch is telephone wires if available.
The largest primate in the region, excluding humans, is the chacma baboon. A true generalist, it is found in virtually all habitats in South Africa. The other primates in the region are the vervet monkey and the Samango monkey. They are mainly frugivores, although they are true opportunists and may take eggs and nestlings from bird nests.
Toxorhynchites, also called elephant mosquito or mosquito eater, is a genus of diurnal and often relatively colorful mosquitoes, found worldwide between about 35° north and 35° south. It includes the largest known species of mosquito, at up to in length and in wingspan. It is among the many kinds of mosquito that do not consume blood. The adults subsist on carbohydrate-rich materials, such as honeydew, or saps and juices from damaged plants, refuse, fruit, and nectar.
The Tana lungfish has a diet not unlike other lungfish, consisting of various mollusks, crabs, prawn, and small fish within its distribution. It can also go for up to 3 1/2 years without any food intake whatsoever. During this time period it behaves much like an estivating fish in that it buries itself in the mud and does not move until more favorable conditions occur.
The island is known for its diversity of mammalian fauna, including several species now extinct or greatly reduced on mainland Australia. 13 mammal species exist on the island, including the spectacled hare-wallaby, burrowing bettong (or boodie), golden bandicoot, black-flanked rock-wallaby, Barrow Island euro and Barrow Island mouse ("Pseudomys nanus ferculinus"). The island is also home to 43 species of terrestrial reptiles including a variety of dragons, legless lizards, geckos, skinks, snakes and monitors. The most recognisable of these is probably the perentie, Australia's biggest lizard and the island's top predator. The island represents important turtle nesting habitat for the green turtle and flatback sea turtle.
Southern Ontario has a very different climate from the rest of the country. It is the only area of Canada that has Carolinian forest. Many trees, plants, and wildlife in Southern Ontario are not found anywhere else in Canada. Some rare trees to Canada in this region include the tulip tree, pawpaw fruit tree and the cucumber tree. The Carolinian forests of Southern Ontario have in large part been destroyed by development sprawl. Very few original growth areas remain.
The forests are home to a number of endemic species including two flightless birds that no longer survive in the lowland areas of the island, these are the western weka and the largest kiwi, the great spotted kiwi. The varied habitats in the region support a mixture of other birds found here include the kea, the New Zealand kaka parrot" (Nestor meridionalis)", the New Zealand pigeon or kereru "(Hemiphaga novaeseelandiae)" and the New Zealand falcon or karearea "(Falco novaeseelandiae)". Farewell Spit in particular is an important site for wading birds and is on a migration route. 
The area is also rich in invertebrates including almost half of the known species of amber snails "(Powelliphanta)".
Though Carnivora is a taxon for species classification, no such equivalent exists for omnivores, as omnivores are widespread across multiple taxonomic clades. The Carnivora order does not include all carnivorous species, and not all species within the Carnivora taxon are carnivorous. It is common to find physiological carnivores consuming materials from plants or physiological herbivores consuming material from animals, e.g. felines eating grass and deer eating birds. From a behavioral aspect, this would make them omnivores, but from the physiological standpoint, this may be due to zoopharmacognosy. Physiologically, animals must be able to obtain both energy and nutrients from plant and animal materials to be considered omnivorous. Thus, such animals are still able to be classified as carnivores and herbivores when they are just obtaining nutrients from materials originating from sources that do not seemingly complement their classification. For instance, it is well documented that animals such as giraffes, camels, and cattle will gnaw on bones, preferably dry bones, for particular minerals and nutrients. Felines, which are usually regarded as obligate carnivores, occasionally eat grass to regurgitate indigestibles (e.g. hair, bones), aid with hemoglobin production, and as a laxative.

"Phytoplankton are eaten by zooplankton - small animals which, like phytoplankton, drift in the ocean currents. The most abundant zooplankton species are copepods and krill: tiny crustaceans that are the most numerous animals on Earth. Other types of zooplankton include jelly fish and the larvae of fish, marine worms, starfish, and other marine organisms". In turn, the zooplankton are eaten by filter-feeding animals, including some seabirds, small forage fish like herrings and sardines, whale sharks, manta rays, and the largest animal in the world, the blue whale. Yet again, moving up the foodchain, the small forage fish are in turn eaten by larger predators, such as tuna, marlin, sharks, large squid, seabirds, dolphins, and toothed whales.
The mandrill is an omnivore. It usually consumes plants, of which it eats over a hundred species. It prefers to eat fruits, but will also eat leaves, lianas, bark, stems, and fibers. It also consumes mushrooms and soil. Carnivorously, mandrills mostly eat invertebrates, particularly ants, beetles, termites, crickets, spiders, snails, and scorpions. It will also eat eggs, and even vertebrates such as birds, tortoises, frogs, porcupines, rats, and shrews. Mandrills likely will eat larger vertebrates when they have the opportunity, such as juvenile bay duikers and other small antelope. Large prey are likely killed with a bite to the nape with the mandrill's long canines. One study found the mandrill's diet was composed of fruit (50.7%), seeds (26.0%), leaves (8.2%), pith (6.8%), flowers (2.7%), and animal foods (4.1%), with other foods making up the remaining (1.4%).
"Stankervision" also features some cartoons, but in "Stankervision" style. One regular such cartoon is about the adventures of "Inebriated the Koala", which was created by Waco O'Guin in 1993 and is introduced as "everyone's favorite eucalyptus-eating marsupial", to which the koala replies "Eucalyptus? You can lick THIS!" as he points to his crotch.
A long-lived tree, "Eucalyptus robusta" can live for at least two hundred years. Trees regenerate by regrowing from epicormic buds on the trunk after bushfire. The grey-headed flying fox ("Pteropus poliocephalus") eats the flowers, and the koala ("Phascalarctos cinereus") eats the leaves. "Eucalyptus robusta" appears to be one of several key species of eucalypt for the koala in the Shire of Noosa in Queensland. The musk lorikeet feeds on the nectar of the blossoms. It is a keystone species on the New South Wales Central Coast and Illawarra regions, where it is one of few reliable winter-flowering plants. Stands of "E. robusta" have been drastically reduced by land clearance. Some remnant trees in Robson Park in the Sydney suburb of Haberfield are the last vestiges of the Sydney Coastal Estuary Swamp Forest Complex community in Sydney's inner western suburbs.
"Eucalyptus saligna" regenerates by regrowing from epicormic buds on the trunk and lower branches after bushfire. Trees live for over two hundred years. The grey-headed flying fox ("Pteropus poliocephalus") eats the flowers, the koala ("Phascalarctos cinereus") eats the leaves, and crimson rosella ("Platycercus elegans") eats the seed. The longhorn beetle species "Paroplites australis", "Agrianome spinicollis" and "Tessaromma undatum" have been recorded from the Sydney blue gum.
Omnivores are usually generalists. Herbivores are often specialists, but those that eat a variety of plants may be considered generalists. A well-known example of a specialist animal is the koala, which subsists almost entirely on eucalyptus leaves. The raccoon is a generalist because it has a natural range that includes most of North and Central America, and it is omnivorous, eating berries, insects, butterflies (Hackberry Emperor, for example), eggs and small animals. Monophagous organisms feed exclusively, or nearly so, on a single other species.
