Several scientists believed they were extinct until two Indonesian scientists trapping rats in the highlands of Sulawesi accidentally trapped and killed a pygmy tarsier in 2000.

A pygmy tarsier, furry Furby/gremlin-looking creatures about the size of a small mouse and weighing less than 2 ounces, being held in one hand.
Sharon Gursky-Doyen, working with one of her graduate students, Nanda Grow, and a team of locals trapped three of the nocturnal creatures in Indonesia in late August. The pygmy tarsiers possess fingers with claws instead of nails, which Gursky-Doyen says is a distinguishing feature of this species, and distinguishes them from nearly all other primates which have nails and not claws. The claws may be an adaptation to the mossy environment, she believes.
