There are currently around 16 recognized species of tarsiers. These species are distributed across Southeast Asia, specifically in the islands of Borneo, Sumatra, Sulawesi, and the Philippines. However, please note that the taxonomy and classification of tarsiers are subject to ongoing research, and new species may be discovered or existing classifications may be revised in the future.
Some of the well-known tarsier species include:
1. Philippine tarsier (Carlito syrichta): Found in the Philippines, particularly in Bohol, Leyte, Samar, and Mindanao.
2. Bornean tarsier (Tarsius bancanus): Found in Borneo, which includes parts of Indonesia, Malaysia, and Brunei.
3. Spectral tarsier (Tarsius tarsier): Found in Indonesia, specifically in Sulawesi, Siau, and Sangihe Islands.
4. Dian's tarsier (Tarsius dentatus): Found in Sulawesi, Indonesia.
5. Pygmy tarsier (Tarsius pumilus): Found in Central Sulawesi, Indonesia. This species was thought to be extinct but was rediscovered in 2008.
These are just a few examples, and each species of tarsier possesses unique characteristics and adaptations specific to its environment. Ongoing research is helping scientists better understand the diversity and conservation needs of tarsier populations.
