The happiest animal in the world, the quokka, sleeps with a smile. Is it trying to laugh itself awake?

When it comes to the happiest animal in the world, if it's not the first, then naturally, all the animals that cry will be the second, because compared to it, others are like crying, at best, they can only manage a bitter smile. Here, the little guy who grew up on the world's sweetest laughter is the Short-tailed Dwarf Kangaroo, scientific name: Setonix brachyurus, also known as Quokka. So in nature, there is a laughter called the "Quokka smile," which can be considered the Mona Lisa's smile of nature. It is so sweet that it can penetrate into the bone marrow and heal the troubles of the day. The author thinks that whether you are happy or temporarily depressed, you can raise one to make your life full of sunshine every day, hug the sunshine to sleep, be awakened by the sunshine, and how can life not be sunny? Are you touched? As for where to find them, they mainly live in Australia and are now listed as endangered protected animals in Australia. The author boldly speculates that it may be because their smile is too sweet, and everyone wants to have one. Therefore, it may have laughed itself out of existence. Happiness is innocent, but excessive greed can lead to dire consequences for them. Hopefully, they can hold onto their paradise so that when we dream of that place at night and see them, we can also wake up with a smile. Indeed, the title of the happiest animal in nature is well-deserved. Even when sleeping, it can smile so sweetly. Thinking about ourselves, the last time we laughed in our sleep should have been when we were children. It seems that only the laughter of the purest soul can be so sweet, and the Short-tailed Dwarf Kangaroo is like a carefree child. Happiness is an essential part of every day, and suddenly I thought of a sentence, "I am responsible for raising you, and you are responsible for being happy." Indeed, these little guys are always either smiling or being funny, too cute! I confess that I have become a fan. After all this talk, let me share some knowledge with you. The Short-tailed Dwarf Kangaroo is a small kangaroo, the only member of the dwarf kangaroo family, about the size of a domestic cat. It is a herbivorous animal and often active at night. Short-tailed Dwarf Kangaroos live on some small islands off the west coast of Australia, mainly concentrated on Rottnest Island near Perth and Bald Head Island near Albany. They live in groups on a small piece of land in the Two-Person Bay Nature Reserve, coexisting with Gilbert's Potoroo. They generally weigh between 3-5 kilograms, are about 40-55 centimeters long, and have a tail length of 24-30 centimeters. They are robust in build, with round ears and short, wide heads. Although very small...

They are generally nocturnal and feed on a variety of plants, including grasses, bark, leaves, and stems. Their diet also includes some fruit and insects. They have a unique digestive system that allows them to extract as much nutrition as possible from their food.

Quokkas have a relatively short lifespan, with most living between 5 and 10 years. They reach sexual maturity at around 1 year of age, and females give birth to a single joey at a time. The joey stays in its mother's pouch for several months before emerging to explore the world on its own.

Despite their friendly and approachable demeanor, quokkas are wild animals and should be treated with respect and caution. Feeding or touching them is illegal in Australia and can result in a fine. Visitors to Rottnest Island are encouraged to enjoy the quokkas from a safe distance and to refrain from disturbing their natural habitat.
