Koalas possess a dominant and unique nose on their face. The koala's nose appears to be spoon-shaped and black in color. Learn interesting features about the koalas' nose.
A novel, non-invasive method of identifying koalas in the wild. Koalas can be easily and non-intrusively identified by the natural black and white markings inside their nostrils. The nose pattern is stable over their lives, and unique to each individual, and applies to koalas right across their range.
This method has been peer-reviewed and published in full (Open Access) in CSIRO Wildlife. The Koala's unusually large, leathery nose is one of its most noticeable features. Koalas rely on their highly developed sense of smell to differentiate levels of toxins in eucalyptus leaves, to detect the levels of toxicity in the leaves at any particular time.
They also need to smell the scent warnings put on trees by other Koalas. A male koala's breeding season bellow. Video: Denise Dearing.
In this photo you can see a male koala's triangular sternal gland, and its odour is an unmistakable badge of identity for each koala. But using nose pigmentation patterns is less invasive, and more people can be involved in the method to help koala conservation, according to McBee. Based on this method, researchers can recognize and identify individual koalas by observing unique pigmentation spots and determining symmetry when compared to previously taken koala photographs.
Fun facts about koalas - Polar Star and the lack of melanin on her nose Due to her partial albinism, Polar Star's fur is paler than her peers, her nose is a light brown/pink compared to black in her peers and her eyes are pale blue instead of brown. Polar Stars light brown/pink nose is due to the absence of melanin. Melanin provides protection against the sun's harmful rays.

Each koala has a unique pattern on their nose. The koala has a broad, dark nose [35] with a good sense of smell, and it is known to sniff the oils of individual branchlets to assess their edibility.

The cuddly, tree-dwelling koala is an iconic Australian marsupial, instantly recognizable by its fluffy ears and button nose. But have you ever stopped to consider the precise shade of their fur? While most people associate koalas with a single color, the truth is far more nuanced.
Understanding the diverse range of colors found in koala populations can shed light on their adaptations. The koala's nose is distinctive - it's a big black leathery rectangle in the middle of a round, grey face that's surprisingly soft to the touch. And every koala nose is unique.
A study of 108 wild koalas found distinctive patterns of pigmentation around the nostrils allowed observers on the ground to reliably recognise individual animals, even when they're in the trees. This article.
