Koalas

Yes. A platypus is a secondary consumer. Secondary consumers are animals that eat primary consumers, and although platypuses do not eat fish, they do eat other primary consumers such as crustaceans, insect larvae and annelid worms.

To begin with, koalas are not bears.

Secondly: no, they do not sleep upside down. They have specific structural adaptations for trees, which do not include any method of sleeping upside down, as they do not have tails. Koalas have sharp claws with opposable thumbs. This gives them extra grip for staying in trees. They also have thick padding on their bottom which helps them to sit comfortably in trees.

Koalas live in exactly the same place during winter as they do in summer, and that is in eucalyptus trees. Despite the changing seasons, koalas do not need to change where they live, as they are well equipped physically for cold winter nights and hot summer days.

These two species of animals are not related (family-wise) at all and therefore it is safe to say that they are not similar. That being said, there are similarities between the two as both species are mammals and herbivores.

Koalas are found naturally only in the eastern mainland states of Queensland, New South Wales and Victoria.

Koalas were originally found in all Australian states except for Tasmania. European settlement saw them wiped out of Western Australia and South Australia, but new colonies have been reintroduced in both states.

Koalas have brown eyes (not yellow as is sometimes reported). They are born with a slightly blue tinge, but this tends to fade as they get older. An exception to this is a joey born at one of Australia's theme parks, Dreamworld, named Logan, but nicknamed "Frankie" for his intense blue eyes.

In Australia koalas that live in the wild have no natural predators. They are in fact at the top of the food chain in their habitat. Large birds such as owls have been known to prey on baby koalas, although such information is scarce. By definition koalas eat only eucalyptus leaves, they do not prey on other animals.

No: on the contrary, koalas are arboreal, or tree-dwelling marsupials.

Koalas live in native Australian sclerophyll forest, commonly known as eucalyptus bushland. Within this bushland, koalas do not have any particular ecological role, as they are not pollinators, and nor do they modify their environment in any significant way.

Koalas feed by climbing certain species of eucalyptus trees which are their favoured types. They reach out to grab leaves (and occasionally, eucalyptus blossoms) with their paws, which have opposable thumbs and enable them to grip their food.

The koala has short, thick fur which is various shades of grey, sometimes with a tinge of almost red-brown.

Koalas have a woolly light to dark grey fur with brown and white patches and a cream belly. They have a broad head with small eyes, large furry ears and a distinctive large black nose. Females has two teats and a rear opening pouch. Northern koalas can grow to 740 mm and 9 kg for males and 720 mm and 7.25 kg for females.

Southern koalas can grow to 820 mm and 15 kg for males and 730 mm and 11 kg for females.

Yes. Koalas are marsupials, which belong to the group of animals known as mammals. All mammals feed their young on mothers' milk. For the first few months of their lives, young koalas (joeys) feed exclusively on mothers' milk.

Koala joeys drink mother's milk during their first 6-7 months of life. After 30 weeks, the mother produces a substance called pap. This substance is actually a specialised form of the mother's droppings which, having passed through her digestive system, give the joey the enzymes it needs to be able to start digesting the tough gum leaves, making an easier transition for the baby koala to start eating eucalyptus leaves.

Koalas are found in a range of temperatures.

They inhabit southern Victoria, where winter minimum temperatures easily drop to just a couple of degrees Celsius (0 degrees is freezing point) but summer temperatures exceed 36 degrees Celsius on a regular basis.

Koalas also live in the north, where temperatures range from 12 degrees Celsius to 35 degrees and sometimes higher.

One of the strangest animals in the world is the Australian Platypus, A monotreme that is it is a mammal that lays eggs suckles its young has the bill of a bird an electronic guidance system for murky water and even sports a poisonous spur to ward of predators

The colour of a koala enables it to blend in with the blue-grey of Australian gum trees. The camouflage effect is further enhanced by the dappled sunlight filtering through the leaves and branches - this tends to make the koala very difficult to see. It was eleven years before the first European settlers in Australia saw a koala or knew of their existence.

Koalas have a gestation period of approximately 33-35 days. They are born very undeveloped, barely half a gram in weight and about 2 cm long, and crawl by instinct to the mother's pouch. Here, it latches onto a teat which then swells in the joey's mouth, securing it firmly in place. Koala joeys will spend six to seven months growing and developing in the pouch before they then cling to their mother's back.

Koalas are indigenous to Australia and live in tropical to temperate eucalypt forest and woodlands and can be found along the eastern and south-eastern coastal regions. They live in eucalyptus trees and are mostly nocturnal and eat certain types of eucalypt leaves exclusively. They breed from September to February. Females breed from 2 years of age, and males from 3-4 years after they have established their own territory. Males are extremely aggressive during mating periods. Thirty-five days after mating, the female produces one joey weighing about 0.5 grams and about 2 cm long. Koalas have a woolly light to dark grey fur with brown and white patches and a cream belly. They have a broad head with small eyes, large furry ears and a distinctive large black nose. Females has two teats and a rear opening pouch. Northern koalas can grow to 740 mm and 9 kg for males and 720 mm and 7.25 kg for females.

Southern koalas can grow to 820 mm and 15 kg for males and 730 mm and 11 kg for females. They can live for up to 18 years for females and a bit less for males. They spend up to 20 hours per day sleeping and the rest eating. Koalas can leap up to 2 metres and can swim. They curl up into a ball to keep warm and spread out to keep cool.
