The world's weirdest animals

And where to spot them:

The western tarsier - The huge eyes of this pocket-sized primate - each bigger than its brain - are surely nature's most outlandish night vision goggles, while it's huge feet and powerful back legs mean it is capable of leaping from tree to tree in search of insects and small invertebrates. The tarsier is native to Borneo and parts of Sumatra.
