Amazing World

Quokka is a small marsupial that lives mainly on islands off the coast of Western Australia. Because of its tiny size, round face, and what looks like a constant smile, it has earned the nickname “the world’s happiest animal.” Photos of quokkas often go viral online because they appear cheerful and friendly in almost every picture.

Their “smile” is actually the natural shape of their mouth and facial structure, which gives them that happy expression all the time. Quokkas are also known for being curious and surprisingly comfortable around humans, especially on places like Rottnest Island where they are commonly found.

Another reason quokkas thrive there is that the island has very few natural predators, which allows them to live more safely compared to many other small animals. They spend most of their time eating plants, leaves, and grasses and are mostly active at night.

Even though they look friendly, they are still wild animals and are protected by law in Australia. Visitors are encouraged to admire them from a distance and avoid feeding or touching them.

Many dog owners notice their dog’s paws moving, legs twitching, or even soft barking sounds while they are asleep. According to research in animal behavior, dogs experience sleep cycles that are very similar to humans. During a stage called REM (Rapid Eye Movement) sleep, the brain becomes very active, and this is when dreaming usually happens.

Studies suggest that dogs often dream about their daily experiences. Since you are one of the most important parts of your dog’s life, scientists believe that many dogs dream about their owners. When their paws twitch or move, they may be imagining running, playing, or spending time with you.

This behavior is completely normal and actually shows that your dog is having a healthy sleep cycle. Puppies and very active dogs tend to twitch more often because their brains are processing lots of new experiences from the day.

So the next time you see your dog’s paws moving while they sleep, it could be a sweet dream about chasing a ball, going for a walk, or happily playing with you.

Squirrels may seem busy and playful, but they play an important role in protecting forests. Every year, squirrels collect and bury thousands of acorns and nuts to store food for the winter. This behavior is called “caching.” They carefully hide their food in small holes across wide areas so they’ll have supplies when resources become scarce.
However, squirrels don’t remember every single hiding spot. While they have impressive spatial memory, many buried acorns are never retrieved. Over time, these forgotten seeds can sprout and grow into new trees. In this way, squirrels accidentally help plant and spread forests.
By transporting seeds far from the original tree, squirrels also increase the chances of healthy growth, since the seedlings are less likely to compete directly with the parent tree. What looks like simple food storage actually supports forest regeneration and biodiversity. These small animals prove that even everyday survival habits can have a powerful and lasting impact on the environment.
