Koalas

There is nothing in eucalyptus leaves that makes koalas sleepy. Eucalyptus leaves are low in proteins and almost indigestible. Koalas have a very low metabolic rate, which is needed to help them digest the leaves and ensure they get as much nutrition as they can from a diet on which other mammals cannot survive.

Koalas are hunted by dingoes, wild domestic dogs and foxes. Goannas, wedge-tailed eagles, and large owls are a danger to baby koalas. To escape their enemies, koalas on the ground run to and climb up the nearest tree.

22 hours x 365 days = 8030. A koala may sleep up to 8030 hours in a year. Add another 22 hours for a leap year.

The koala's average body temperature is about 97.9 degrees F. That is significantly lower than many mammals of its size and weight.

First point is that every bird I can think of hunts animals, since fish, birds, reptiles, insects and mammals are all animals and I don't know of any leaf eating birds. So as such the question you are asking needs to be rephrased a touch, but I think you are trying to specify larger prey i.e not worms or insects. The first indicator of this is size: obviously to lift something as large as a rabbit, the bird itself has to be fairly large, but since migratory birds are also unusually large this isn't the only factor. Beak shape is another indicator, but this too isn't without its problems when one shape of beak is adapted for fish, another for mammals and so on. The key indicator is the claws. Birds don't swoop down and catch prey in their beaks, they grab it in their talons. Birds which truly hunter their prey have an additional claw in each leg similar to that of a dog, fixed into the leg unable to be moved but still useful for pinning the prey against.

No. Koalas do not yield wool. However, during the late 1800s and early 1900s, koalas were noted almost to extinction for their pelts because there was great demand in the USA and the UK for koala fur.

There are two major differences between northern and southern koalas: size and colour.

Koalas in northern parts of Australia are smaller, with males growing to 74 cm and weighing 9 kg, and females growing to 72 cm and weighing 7.25 kg. Southern koalas are larger. The males can grow to 82 cm and 15 kg whilst females can grow to 73 cm and 11 kg.

Northern koalas have woolly light to dark grey fur with brown and white patches and a cream belly. Southern koalas tend to have fur that is darker and tending more towards brown. Their fur is also longer and shaggier, especially on their ears.

The Aboriginal people used them as a source of meat. Various animals including dingos, dogs, foxes and cats will also take them when possible and smaller koalas can be taken by snakes, and larger birds such as eagles, hawks, kites and falcons, etc.

No, a raccoon has the same senses as most animals - sight, hearing, smell, taste and touch. However, some of the raccoon's senses are enhanced. Their hearing is quite acute and they can hear earthworms and grubs digging underground. They, also, have very good sense of smell and touch.

Any animal that hunts and eat other animals is a predator, and a carnivore.

Another animal that might eat a predator - if it's already dead - is a Scavenger.

The koala joey stays in the mother's pouch for several months, until it has developed enough to climb out from within the safety of the pouch. After that, it spends several more months clinging to its mother's back.

Koalas are herbivores which eat eucalyptus leaves. Their front teeth, which they use for nipping off the leaves and gum blossoms, are quite sharp. Their molars, however, and flat and strong for chewing the leaves.

How long baby koala bears stay with their parents can vary depending on how often the mother reproduces. On average, the koala bear stays in its mother's pouch for five to seven months.

The male koala has a scent gland which he uses to rub against the trunk of a tree. He scent marks to indicate his home trees, and this is to attract the female. Koalas have a range of around one square kilometre, and they have numerous home trees within that territory. Male koalas use scent marking to have a possible mating with females who then pick up their scent from the tree trunks.

Koalas are mammals, and most mammals have skin, either with or without fur or hair. In the case of the koala, the fur has particular functions.

The koala's fur helps to keep it cool in summer and warm in winter. Its outer layer is partially waterproof, so that when rains do come, the koala does not become saturated.

The Koala eats eucalyptus leaves, they don't hunt in the traditional sense, they forage.

Koalas do not eat bamboo. The Koala (Phascolarctos cinereus) is a marsupial mammal and is indigenous to Australia. Their closest relative is the wombat. They live in eucalyptus trees and eat only a few types of gum leaves from which they get all nutrients and water requirements. Eucalyptus leaves are tough, toxic and low in nutrition, but the koala has developed a stomach which is capable of removing the toxins from where they are filtered out by the liver. The caecum completes the process by changing the eucalyptus leaves into digestible nutrients. The caecum is similar to the human appendix. The koala must eat over a kilogram of leaves per day to meet its energy requirements. Eucalyptus leaves contain approximately 50% water, 18% fibre, 13% tannins, 8% fat, 5% carbohydrates, 4% protein and 2% minerals. Koalas have been seen feeding in 120 kinds of eucalypt tree including Manna Gum, Swamp Gum, Blue Gum, Forest Red Gum and Grey Gum.

A koala does not have an external tail. At most, remnants of a tail can be seen in its skeleton, but there is no part of a tail visible.

This is similar to a wombat, its closest relative, in which no external tail is visible either.

Humans have a significant impact on koalas.

The main way is through habitat loss. Humans insist on knocking down eucalyptus bushland where koalas live and building housing and suburban developments. With houses and roads come cars and dogs, both of which are lethal to koalas. A case in point - Southeast Queensland in Australia used to be a vibrant koala corridor extending for hundreds of kilometres down the coast and inland, but human population explosion in the area saw a drop of 67% in the koala population between the years 2000 and 2010.

Humans have also introduced new predators which have proven to be a greater threat to koalas than native predators. When Europeans started settling in various parts of Australia, they introduced a variety of non-native predators, such as foxes and dogs, both domesticated and wild. Koalas are no longer safe to wander between the trees in their home range in suburban fringes; they are constantly at risk of being killed by dogs.

Koalas are no more afraid of fire than any other wild animal is, but they sense its destructive force. Bushfires in Australia have the capacity to wipe out thousands of square kilometres of prime bushland, in which koalas live. These fires move rapidly, and the tops, or crowns, of the eucalyptus trees in which koalas shelter and find food literally explode with the flames as the eucalyptus oil inside reaches boiling point.
