I. Introduction:
a. Phascolarctos cinereus is the scientific name of the organism I have chosen for my lab report.
b. The common name in which individuals recognize this particular organism is known as the koala bear.
c. Kingdom: Animal
Phylum: Vertibrata
Class: Mammalia
Sub-Class: Marsupialia
Order: Diprotodontia
Sub-Order: Vombatiformes
Infra order: Phascolarctomorphia
Family: Phascolarctidae

d. Looking at the mammalia class, some of the common characterics organisms within the class have are being endothermic with high metabolism and having hair and mammary glands. The mammary glands are used to produce milk for their young and the hair is used as insulation helping …show more content…
Since koalas have a very low calorie diet, they save all their energy by taking very slow movements and spending most of their time sleeping.
III. Defense: Koalas are able to defend themselves from potential predators by spending the majority of their time up high in trees. Koalas have sharp claws, a strong grip, and rough pads on their hands and feet which make life in these high trees easy for koala bears. If a koala felt as if it was in trouble, it also has two opposable thumbs so that they can cling to branches and even leap from branch to branch to escape the situation. An example of a mutualism in a koala bear is the bacteria in the koalas stomach. This bacteria allows koala bears to get their food without dying from the poison in the leaves. An example of commensalism is the relationship between the koala bear and the eucalyptus tree. The koala bear uses the tree for shelter, and a place to hide from predators. Commensalism is present due to the koala bear benefitting from the tree and the eucalyptus tree is a neutral …show more content…
Adaptations: Living in forests, Koalas are about to survive due to numerous adaptations. One interesting adaptation a female koala has is the usage of marsupials, or pouches on their bellies. These pouches help to raise their young while living atop trees. Another adaptation koalas have is the thick fur which covers their bodies. This thick fur makes living in trees much more comfortable. When looking at other parts of the koala bear, the tail end of its body is covered with more fur than the rest, giving a cushioning effect while sitting on branches. Koala bears also have a curved spine. This curved spine also works towards making sitting on tree branches a more comfortable
