Philippine tarsier (Carlito syrichta). The Philippine tarsier is nocturnal; they hunt at night, exclusively for animal prey. At day time, they hide in hollows close to the ground. When kept in captivity, individuals may huddle together or intertwine their tails. They are believed to live in groups, larger than just one male and one female. The female appears to take care for the young exclusively: no male parental care has been observed.
