The first pygmy tarsiers seen alive since the 1920s were found by a research team led by Dr. Sharon Gursky and Ph.D. student Nanda Grow from Texas A&M University on Mount Rore Katimbo in Lore Lindu National Park in August 2008.

[3][4] The two males and single female (a fourth escaped) were captured using nets, and were radio collared to track their movements.

As the first live pygmy tarsiers seen in 80-plus years, these captures dispelled the belief among some primatologists that the species was extinct.

Unlike other nocturnal species, tarsiers lack a tapetum lucidum due to the diurnal evolutionary history of primates.

[9] The pygmy tarsier is endemic to the mossy cloud forests of central Sulawesi, Indonesia and found at altitudes of 1,800–2,200 m (5,900–7,200 ft).

[2] Due to their arboreal lifestyle, their diet consists of airborne insects found in the forest canopy such as moths, grasshoppers, and katydids.

Some species of tarsier have recently been found to communicate at ultrasonic frequencies of around 70 kHz on the islands of Bohol and Leyte.
