What is the Scientific Name of the Koala
- Scientific Name: Phascolarctos cinereus
- Pronunciation: fas-ko-LARK-tus sin-EER-ee-us
- Common Names: Koala, Koala Bear (incorrect but common)
- Koala Bear Scientific Name: Same as above (Phascolarctos cinereus)
The Koala Scientific Name Pronunciation
Phascolarctos cinereus is pronounced like this:
- fas-ko-LARK-tus sin-EER-ee-us
- Phascolarctos: Phascol (pouch) + arctos (bear)
- Cinereus: Latin for ash-colored, regarding the soft grey fur of the koala
The term bear refers only to the general likeness of the animal to a bear and not to the class it represents.
What Does the Koala’s Scientific Name Mean?
The scientific name is from Greek and Latin roots:
- Phaskolos (Greek): Pouch
- Arktos (Greek): Bear
- Cinereus (Latin): Ash color
Thus, we get the meaning of Phascolarctos cinereus, i.e. ash-colored pouch bear. This denotes either the marsupial pouch of the koala or the grey fur tone, besides differentiating koalas from placental mammals like bears and monkeys.
Koala Biological Classification
| Taxonomic Rank | Classification |
|---|---|
| Kingdom | Animalia |
| Phylum | Chordata |
| Class | Mammalia |
| Infraclass | Marsupialia |
| Order | Diprotodontia |
| Family | Phascolarctidae |
| Genus | Phascolarctos |
| Species | cinereus |
Koalas are the only surviving species in their family, making their evolutionary lineage highly unique among marsupials.
Baby Koala Name And Growth
- The name of the baby koala is Joey.
- At birth, it measures the coarseness of a jelly bean, and it is completely blind and hairless.
- The time spent by a joey in the pouch of its mother is not less than 6 months.
- After this, the joey rides on the back of the mother and eats ‘pap’, which is an immaturely digested nutrient-rich eucalyptus substance used to prepare the joey’s stomach for leaves.
Where Do Koalas Live?
Koalas are natives of Australia and inhabit the following eucalyptus:
- Queensland
- New South Wales
- Victoria
- South Australia
Highly territorial by nature, koalas live through their entire life in a portion of space called ‘home range’, that can cover several trees.
What Do Koalas Eat?
- Basic Diet: Eucalyptus leaves
- Diet Type: Herbivorous
- Favorite Species: There are over 600 species of eucalyptus, with koalas being avid eaters of about 30.
- Digestive System: Koalas have a specialized caecum and gut bacteria that neutralize the toxic compounds in eucalyptus.
- Hydration: They consume very little water and get most of it through plants.
- Waste: Eucalyptus leaves are a poor source of nutrition. Therefore, koalas sleep 18 to 20 hours a day to conserve their energy.
Koala body traits
Koalas have physical traits that fit life in trees.
The Australian Museum lists a common length of around 68 to 82 cm. They have thick ash-gray fur. Their head looks round. They also have big ears and strong legs. These traits help them stand out from other animals in Australia.
Their hands and feet are made for climbing. The way their fingers and toes are shaped helps them hold onto tree limbs. They can then move through the canopy with more ease.
Koalas also have teeth built for plant food. These teeth let them handle tough leaves and chew tough plant parts.
