The Western Pygmy Possum is a small marsupial native to southwestern Australia. It typically measures about 7 to 10 centimeters in body length, with a tail that can be as long as its body. This species has a soft, grayish-brown fur and large eyes, which help it navigate its environment, especially at night. These possums primarily inhabit woodlands and shrublands, where they feed on nectar, fruits, and insects. They play a crucial role in pollination, particularly of banksia flowers. The Western Pygmy Possum is known for its ability to enter a state of torpor, allowing it to conserve energy during colder months.
