Its eyeball is bigger than its brain.
From Wikipedia: "Tarsiers have never formed successful breeding colonies in captivity, and when caged, tarsiers have been known to injure and even kill themselves because of the stress. One site having some success at restoring tarsier populations is in the Philippine Island of Bohol. The Philippine Tarsier Foundation has developed a large semi-wild enclosure that uses lights to attract the nocturnal insects that make up the tarsier's diet."
