A Marcupo or Makupo is a giant serpent in Philippine mythology (specifically among the Hiligaynons).
Its characteristics include a prominent red crest on its head, a long tongue with thorn like hairs, sharp tusks, and a forked tail. It is said that the Marcupo can spit venom much like a cobra. Moreover, it is also known to sing sonorously during quiet days. Its main habitat is in heavily forested mountains.
A Marcupo can measure approximately 45 feet long and is estimated to weigh around 2500 pounds.
