Proboscis monkey

Here's an amazing thing about the proboscis monkey: the leader of the herd searches for danger and when it finds danger, with a blow of its big old nose, it'll tell the herd to run away. And the honk that it does with its nose is called "the core honk." And here's an extremely amazing AND rare thing about these monkeys: they have webbed feet which are useful for swimming away from its predator, the gharial (a relative of the alligator). Well here's how a gharial would probably get to its delicious proboscis monkey lunch: well, you see, if the monkey is in water, that is just one way of attacking. But you know how fast creatures like this can strike. So if one is maybe sort of just at a thin branch up, just over  a stream or something, then the gharial might be able to attack.
