About Quokka Facts: The Happiest Animal on Earth

Quokkas are small marsupials native to Western Australia famous worldwide for their adorable smiling facial expressions. These friendly herbivores measure sixteen to twenty one inches long and weigh five to eleven pounds.

Why They Appear to Smile Constantly

Quokkas have become internet celebrities due to their seemingly smiling faces. The upward curve of their mouths combined with small rounded ears and bright eyes creates an expression that appears cheerful and friendly. This facial structure is simply natural anatomy rather than an indication of emotion.

How Ten Thousand Live on Rottnest Island

Quokkas once ranged across southwestern Australia but now exist in limited fragmented populations. The largest stable population lives on Rottnest Island a small island off Perth's coast. Between ten thousand and twelve thousand quokkas inhabit this seven square mile island.

Why They Survive Months Without Water

Quokkas are herbivores that eat a variety of plant materials. Their diet consists primarily of grasses, leaves, bark, and stems. They prefer new growth and tender vegetation when available.

How They Hop Twenty Miles Per Hour

Quokkas are generally solitary animals though they sometimes gather in small groups near good food sources. They are not highly social and do not form lasting bonds beyond mother offspring relationships. Males are territorial and defend home ranges from other males.

Why Joeys Stay in Pouches Six Months

Quokkas breed year round on Rottnest Island though most births occur in late summer. Females reach sexual maturity around one to two years old. After a brief twenty seven day gestation period females give birth to a single tiny joey.

How Selfies Made Them Internet Famous

Quokka selfies have become a popular trend with celebrities and tourists sharing images worldwide. This friendly behavior combined with their photogenic faces creates perfect conditions for close up photography. The appearance has made quokkas extraordinarily popular on social media platforms.
