Evening nature program.
TV presenter: Megane zaru.
Foreign guest: In English?
TV presenter: Tarsier. 12 centimeter monkey. Spectacle monkey, if you will.
Foreign guest: Big eyes.
TV presenter: Cranium is mostly eye socket. They leap from tree to tree and as they land they close their eyes.
Foreign guest: Understandable. Close their eyes to protect them as they sink their teeth into their prey.
TV presenter: True. But you know, their eyes are fixed in a straight-ahead direction. Can’t swivel their eyeballs like humans. Like owls.
Foreign guest: Why not?
TV presenter: And another thing. They can leap 3 meters from tree to tree.
Annoying thing about presenters, who present on a different topic every night, is that they give you a surprising fact and since they can’t say why, they dart on to the next feature. It’s the nature of TV.
Tarsiers' eyes are enormous and unique, aside from their non-swivelling characteristic; some neuroscientists believe that "they arose from an early, independent primate line of evolution" (WikiP). Could be a connection there.
