Introduction
Koalas are well known mammals. Koalas have bilateral symmetry, are multicellular, and are typically slow movers. One theory is that although koalas can swim and move on land, it is believed that they used to be able to do more. Koalas are slow movers and have adapted to mostly living in trees. So this makes this harder for predators to hunt them as prey. They consume many different types of plants, spend most of their times in trees where their main source of food is abundant, and they eat plants that other animals are unable to eat. Koalas have been able to withstand many different diseases such as chlamydia. Koalas are tree dwelling, plant eating marsupials, meaning that that females have a pouch to carry young. They have strong

cinereus typically inhabit open eucalypt woodlands. They are found in a range of habitats, from coastal islands and tall eucalypt forests to low woodlands inland. . Koala populations only occur if suitable habitat is available. The two most important factors which make habitats suitable are the presence of tree species preferred by Koalas growing in particular associations on suitable soils with adequate rainfall and the presence of other Koalas. Research shows that stable Koala populations occur only when there are primary tree species present. (Australian Koala Foundation) Habitat destruction plays a big role in the survival of P. cinereus in urban areas. Construction destroys their habitats and food supply, causing a rapid decrease in the koala population that inhibit highly populated areas. They also become prone to disease, and reproduction rates decrease in accordance to human …show more content…
Females generally start breeding at about three or four years of age and usually produce only one offspring each year. However, not all females in a wild population will breed each year. Some produce offspring only every two or three years, depending on factors such as the age of the female and the quality of the habitat. (Ryan) In the average female's life span of about twelve years, this means that one female may produce only 5 or 6 offspring over her lifetime. Once a female has conceived it is a short 35 days before the birth of the new baby, called a "joey". The tiny baby which is roughly 2 centimetres long and weighs less than 1 gram is totally hairless, blind and has no ears. (Charlton 2011) The joey makes its way from the birth canal to the pouch completely unaided, relying on its already well-developed senses of smell and touch, strong forelimbs and claws and an innate sense of direction. Once inside the safety of the pouch, it attaches itself to one of the two teats, which swells to fill its mouth. (Ellis 2010) This prevents the joey from being dislodged from its source of food. The young Koala drinks only mother's milk for the first six to seven months. (Whisson 2010) Once the koala is ready it leaves the mother’s pouch and begins to ride on her back. On her back, the joey begins to feed on leaves for
Koalas are arboreal mammals, meaning that they live in trees. They live in eucalyptus trees and feed on their leaves, which are poisonous to most animals. A koala’s home is decided by two main factors: the presence of other koalas and eucalyptus trees. They can eat other tree leaves, but that usually occurs only when eucalyptus leaves are absent (Crawford n.d.).
They don't breed until they are between six and eight years old, and the female lays only one egg every two years. If that egg is removed, however, she will lay a second or a third. With this in mind, scientists captured wild condors for captive breeding and also began to collect eggs for captive
Koala bears have really unique lives and that's what makes them special. The habitat they live in is usually eucalypt forests. Another place could be in the woodlands. Where they sleep for most of the day is in trees. The way their family is set up is not always with each other. Even though they live in the same tree and forest they mostly sleep. Once the baby is born it is in the
Habitat: Partially or completely open country, around mountains, hills, and cliffs. They use many different habitats ranging from arctic to desert, some include tundra, shrub lands, grasslands, coniferous forest, farmland and rivers or streams. They can be found in Mexico, North America, Alaska, and sometimes Asia, northern Africa, and Europe. They nest in high places such as cliffs, trees, or human structures. They build huge nests that they may return to for several breeding years.
How Koalas Live Koalas live in complex social groups and contrary to popular opinion, they are not migratory animals. Koalas are highly territorial and in stable breeding groups, individual members of koala society maintain their own "home range" areas. In this example , 'Arnie' is the dominant male, and his home range, the largest at 1km x 300-400m, and 33 hectares in area, overlaps the home ranges of both males and females. Arnie regularly traverses the area of his home range in a single night during the breeding season. This is a socially secure, stable population.
Capybaras can be found in Central and South America which includes countries such as Brazil, Uruguay, Venezuela, and Columbia. They are semiaquatic so they must live by water, this includes swamps, marshes, estuaries, wetlands, and near rivers and streams. They use this water to hide from predators by only showing their eyes and noses above the water. Depending on which area they live in, they will
Koalas are one of the things that a person would think of when they hear Australia. Most people call them koala “bears” but this is a common misnomer. Koalas are more closely related to kangaroos and wombats than bears. Their scientific name is Phascolarctos cinereus. They have evolved and adapted to their environment for survival. Their lifestyle of eating and sleeping, which people think is amusing, is actually a result of their adaptation to the environment. Koalas have physically evolved in various ways to adapt to the environment.
Kinkajous live in forest areas in southern Mexico, Central America, and South America. Forests are a good environment for the kinkajous because they rarely leave the trees. Another reason that forests are a good environment for them is because kinkajous can find their food and needs easily. The kinkajou’s diet consists mainly of fruits. Their main fruit that they eat are figs, but they do eat other foods such as flowers, leaves, and some herbs depending on the season. Kinkajous
Chimpanzees live in many different habitat types. Their habitats include dry savannas, evergreen rainforests, montane and swamp forests, and dry woodland (Cawthon Lang). They are often very adaptable to climate changes and can live in both terrestrial and arboreal environments. Because of the different environments chimps live in, their behaviors are developed based on where they live.
Their offspring is one. The lifespan of the ring-tailed lemur is 20 years. They have a
During the sixth week of pregnancy the crown-to-rump ( referring to the length of the baby from the top of the head to its bottom, this term is used because it 's hard to measure from head to toe because the babies are usually curled up with their legs tucked under.) length of the baby is about 2-4mm long. At this point in the pregnancy some of the facial features are now visible even the mouth and tongue. Also the outline of the jaw is starting to

...side begins to grow and develop at six weeks the baby is only five eights of an inch in measurement. As the months go on the baby goes thru many changes as well as the mother and her body. The mother may tend to get ill at times or may be fine during her pregnancy. There are also reports that the father may become ill at times as well along with the mother, this is common in men.
MATING: Siberian tigers mate in winter months and following a 3-5 month gestation period, the female produces 3-4 cubs. Cubs weigh just over 2 pounds each and are born blind. The small litter of cubs stay close to their mother for the first 8 weeks of life. By 18 months, the young are capable of hunting on their own. Young stay with their mother for 2 years, at which time they leave the pact and travel solo. The life span of the Siberian tiger is 15 years in the wild, and significantly longer in captivity.
This process is called conception, the female is now officially two weeks pregnant and the fertilized egg is called a zygote. Let’s move on to pregnancy. Pregnancy is a state in which a woman carries a fertilized egg inside her body, it usually lasts up to 40 weeks, and it is divided into three trimesters, each lasting three months. The first month. The embryo is about a third of an inch long. The head, trunk, and the beginnings of the arms and legs have started to develop. By this month, the embryo starts to receive nutrients and releases waste through the umbilical cord and placenta. The heart also starts to beat. The second month. The heart is now pumping and the nervous system, including the brain and the spinal cord begins to develop. The fetus is 1 in 2.5cm now and has developed cartilage skeleton. The arms, legs, facial features and other major organs begin to appear. The third month. The fetus has grown up to 4 in 10cm and weighs a little more than an ounce. The major blood vessels are almost completed and the face starts to show up more. The kidneys and the 4 chambers of the heart are now complete. The fourth month. The fetus is now 4 oz of 112g and can kick and swallow. The
