Do You Know the Name of this Weird Creature?

A rat-snake like creature was seen by a farmer in Torrijos, Marinduque, Philippines last Saturday. The farmer was working in his rice field when all of sudden the creature startled him. The animal emitted a weird sound as if calling for a mate or company, according to the farmer. A local veterinarian confirmed that this strange looking animal has never been seen in the Island of Marinduque. It is about 3 meters long with knife-sharp teeth. The three photos was published at http://www.balitangmarinduque.com/2016/11/kakaibang-hayop-natagpuan-sa-torrijos.html

If you know what kind of animal is this, let me know. You could add the above creature to a list of weird and paranormal creatures like the Mexican devil animal-the chupacabra as shown in the following video.
