Filipino Cobra or Python or Anaconda

We are shooting at an abandoned location. Well, though it is abandoned by humans, the local creatures are still hanging out. One of the guys found this 9 foot long skin at like 1am when we were there. It was still wet! Newly sloughed! Yikes. Then one of our drivers told me a story about how his cousin got bit on the mouth by a King Cobra and died! AND someone else saw an anaconda swimming around in one of the old elevator shafts that are now filled with water. Just like the movies. Who needs hollywood when you have Angeles City.
