The Jatna’s tarsier (Tarsius supriatnai ) is a species of tarsier found in Indonesia. Their call, or "songs" are known to be different from other similar tarsier species. The Jatna's tarsier has giant eyes and ears, and they also can rotate their heads like owls. This skill helps them locate predators and prey in the dark. They can also jump like 40 times their body length. This species of tarsiers was named after Dr. Jatna Supriatna because in his professional life, he has spent most of the time talking about the biodiversity in Indonesia and did a lot of work on tarsiers.
