Petaurista elegans, commonly known as the black giant squirrel, is a large species of tree squirrel found in the forests of Southeast Asia. It is characterized by its striking black fur, bushy tail, and large size, typically weighing between 1.5 to 2.5 kg. This species primarily inhabits tropical and subtropical forests, where it is well-adapted to arboreal life. These squirrels are herbivorous, feeding mainly on fruits, nuts, and seeds. They play a crucial role in their ecosystem by aiding in seed dispersal, which helps maintain forest biodiversity. Petaurista elegans is also known for its agility and ability to leap between trees, making it an impressive acrobat in its natural habitat.
