I saw some interesting flora and fauna while in Tanjung Puting. For a city gal like yours truly, they were enough to make me gape for a long time (thankfully I also managed to take some pics).
Proboscis monkeys can swim very well and they can dive gracefully in the river. They sometimes croak "Aow! Aow!"
Mr. Yusup told us not to stare at their eyes, no matter how appealing they are, because to them, it's a sign of aggression. As you can see here, they have sharp teeth and they can be fierce. Since they travel and usually attack in groups, even proboscis monkeys (who are bigger!) are wary of them and avoid them whenever possible.
Unlike orangutans and proboscis monkeys, owa-owas mate for life. They live in small clusters (family). The sound of owa-owas are melodious and usually can be heard in the morning. (to be continued)
