A koala bear’s diet consists almost completely of eucalyptus leaves, however they are known to also eat the stems, flowers and bark of the eucalyptus tree. A koala bear will only eat the leaves of only a few eucalyptus trees and are very picky with their diet and do not like change regarding their diet.
Dental formula of a koala bear: Incisors 3/1; Incisors 1/0; Pre Molars 1/1; Molars 4/4. This adds up to a total number of 30 teeth.
The koala has a space between its incisors and premolars for leaves to be stored until they are ready to be processed by the premolars and molars. The molars and premolars grind the leaves until it forms a paste. This makes it easier for the food to be digested.
The koala's teeth are highly specialized and are a fundamental part of the digestive process. The teeth crush food particles which effectively increases the surface area for the specialized digestive organs
Their incisors are relatively sharp and are used to grab leaves from trees. The large molars are shaped to allow them to cut the leaves, preparing them for further digestion. There is a large space between the incisors and the molars that allows the tongue to move leaves around the mouth.
To make the most of the energy that is taken in in their diet, the koala uses a decreased metabolic strategy that allows it to retain for long periods of time. The highly specialized digestive organs of the koala have adapted in the way that it withdraws the required nutrients from the poorly balanced diet.
The Koala's digestive system is also adapted to detoxify the poisonous chemicals in the leaves. Koalas have a special fibre-digesting organ called a caecum, which is very long (200 cm). The caecum contains millions of bacteria which break down the fib...

Dental formula and total dentition
Their molar teeth are adapted for crushing and not for cutting. Dental formula: Incisors 3/3, Canines 1/1, Pre molars 4/4, Molars 2/2 = 40.
Its dentition is regarded as heavy because of their broad high-cusped cheek teeth are better suited for crushing than slicing. Still have sharp, double edged canines
Teeth shape and size
Raccoons have teeth designed to grind plants or tear meat. They have 4 long, sharp canine teeth that are used to tear food and molars to chew food. Since they eat both meat and plants, they have teeth that are necessary in order for both to be digested.
The pH of the stomach in a raccoon is less than or equal to 1.
Most raccoons eat during the night time, as they are nocturnal creatures. They eat every day and are almost always looking for food and eat up to 2kg of food per day.

Koalas, an Australian native, have the scientific name, ‘Phascolarctos cinereus’, meaning 'ash grey pouched bear.' They are sometimes called koala bears due to their resemblance to bears. However, they are not related to each other. Instead, koalas are related to other marsupials, such as kangaroos and wombats. Being a marsupial means that the females have a pouch for newborns. The Australian Koala Foundation estimated that less than 80000 koalas are left in Australia (Australian Koala Foundation n.d.).
Tool-use is regularly reported in chimpanzees. They use many different tools to carry out many different tasks. They use sticks to fish for insects, stones and wood to crack open nuts, leaves to soak up liquid, and branches used as weapons to dominate opponents and frighten off predators. In making tools, they may use a variety of different materials to make the same kind of tool. For example, they use sticks, twigs, bark, and vines to fish for termites. They also may use the same material for different purposes. A leaf could be used as a termite probe, a napkin, or a sponge.
The relationship of the three species and their ancestors can be summarized by looking at the fossils above. It is evident that all of these three species possess fangs and other types of sharp, prominent teeth. These analogous features indicate that there is some similarity in ancestry, since they all form part of the same family group, although they come from different genus. However, there is some difference in the shape of the head. The coyote possesses a straighter jaw and more angular head. The wolf, on the other side, has a wider denture similar to the fox. These three species also share Homologous structures, such as fangs, are present in these species. Another homologous structure is the legs and ribs, since they all have a similar
All primates have essentially the same kinds of specialized mammalian teeth adapted to eating a wide variety of foods. Beginning at the front, each quadrant of the mouth has 2 incisors, 1 canine, and varying numbers of premolars and molars. The incisors are used like scissors for nipping off pieces of food. The pointed canines are for piercing and tearing. The premolars and molars, with their cusps, are used to grind and smash food. In platyrrhine species, there are 3 premolars and 2 or 3 molars. This results in a dental formula of 2.1.3.2 or 2.1.3.3. In contrast, all of the catarrhines have 2 premolars and 3 molars, making a dental formula of 2.1.2.3. The chimpanzee shown below is an Old World anthropoid species and, therefore, has a catarrhine dental formula.
These hard treats are perfect for keeping your dog's teeth clean and preventing tartar build-up. They're hard, cunchy and 100% vegeterian. (You'll need a hammer to break them up for older and smaller dogs)
The females are breeding, and most have a weaned juvenile in the vicinity and another pouch young. The home range of each animal fits together like a jigsaw. This illustrates that the habitat supporting this population is ideal for its survival. However, if the available habitat were to be reduced in any way, the potential for survival of each individual would also be reduced. A 'home range' consists of a number of 'home range trees' and 'food trees' which comprise the long-term territory of the individual koala.
they are at the top of the food chain of the grassland plants and animals. Grizzly bears are powerful, top-of-the-food-chain predators, yet much of their diet consists of nuts, berries, fruit, leaves, and roots. Bears also
Not many people know about the arctic wolf, it is the snowy white version of a wolf. They have a really big appite when it comes to eating. They most only eat one meal a day and eat up to 20 pounds in that one meal. They are mostly carnivores; they mainly eat big animals like the caribou and the musk ox so they can feed themselves and the whole pack (Arctic/Antarctic: The Arctic Wolf). People eat up to three meals a day, but wolves can go up to days with out eating a single thing (Arctic/Antarctic: The Arctic Wolf). When wolves are hunting they have to be able to have a plan to catch their food. Wolves would get all the pack members that are hunting to surround the animal, and pounces on them. One bit to the neck and the animal would be dead. When they are eating they will eat everything, like the meat, shin, fur and bone (Arctic/Antarctic: The Arctic Wolf). Also Arctic wolves can live up to 20 years in captivity, while they can only live 7- 15 years in the wild (Arctic/Antarctic: The Arctic Wolf). Arctic wolves are one of the most prettiest and unique types of wolf. When Arctic wolves are pups t...
African Elephants are considered herbivores, they are both browsers and grazers; they will eat rough sticks, stems and leaves of plants as well as grasses, sedges, and fruit.
There is a wide variety of animals within the deciduous forest. Mammals, birds, reptiles, insects and microorganisms can all be found in the forest, some of the most common animals found are bears, deer, elk, squirrels, skunks and wood mice. Due to vast hunting seasons deer and elk within this biome have become near extinct. Animals migrate and hibernate to adapt to the climates of the deciduous forest, many birds will migrate to better weather and most mammals will hibernate during the months were food is limited. Another behavioural adaptation some animals have learned is storing berries and nuts to last the limited food times. They use the cold weather as almost a fridge because the cold climate helps preserve the berries and nuts for long periods of time.
