Tarsiers are small primates found in Southeast Asia, particularly in the Philippines, Borneo, and Sumatra. They are known for their large, round eyes, which help them see well in the dark, as they are primarily nocturnal. Tarsiers have long fingers and toes that allow them to grasp branches easily, making them excellent climbers in their forest habitats. These unique creatures are also known for their distinctive vocalizations, which can sound like bird calls. Tarsiers primarily eat insects, but they can also consume small vertebrates like geckos and mice. Their fascinating appearance and behaviors make them a subject of interest for both scientists and animal lovers alike.
