Burramys parvus, commonly known as the mountain pygmy possum, is a small marsupial native to the alpine regions of Australia. It is one of the world's smallest possums, measuring about 7 to 10 centimeters in length. This species has a thick, soft fur that helps it survive in cold environments, and it primarily feeds on insects, seeds, and fruits. The mountain pygmy possum is unique for its hibernation behavior, which allows it to conserve energy during the harsh winter months. It is classified as endangered due to habitat loss and climate change, making conservation efforts crucial for its survival.
