Mr. Yaun, what is today’s fun

fact?!?

When nobody was looking, Fu Manchu would use air ducts to get into the dry moat surrounding the exhibit. He then yanked the door to the furnace room open just enough to slide around his homemade key, pop the lock, and escape.

Fu Manchu was so stealthy, zoo keepers began to fear for their jobs, as zoo officials were convinced the escapes were due to employee negligence.

This extraordinary photograph published in the 2008 book "Thinkers of the Jungle: The Orangutan Report" by Schuster, Smits, and Ullal shows the first recorded instance of an orangutan attempting to use tools to hunt.

According to the authors "…a male orangutan, clinging precariously to overhanging branches, flails the water with a pole, trying desperately to spear a passing fish…The extraordinary... image, a world exclusive, was taken in Borneo on the island of Kaja… This individual had seen locals fishing with spears on the Gohong River. Although the method required too much skill for him to master, he was later able to improvise by using the pole to catch fish already trapped in the locals’ fishing lines."
