Borneo Anacondas

The Borneo Anacondas are the main antagonists of the 2004 adventure-horror movie Anacondas: The Hunt for the Blood Orchid.

Description
They are anacondas from Borneo who consumed "blood orchid", a flower that extends lifespans. Therefore, they kept growing for their entire life and became gigantic. The females are much larger than the males.

History
At the beginning of the film, a Borneo Anaconda attacks a native hunter in the jungle. He manages to flee, but he then falls into a river below and is dragged underwater by another Anaconda.

Some times later, dozens of male Anacondas come out of their territories during a mating season to find a female in her pit. However, a team of pharmaceutical researchers consisting of Dr. Jack Byron, Gordon Mitchell, Sam Rogers, Gail Stern, Cole Burris, Ben Douglas, and their guide Bill Johnson and Tran Wu, comes simultaneously in the area to search the "blood orchid". During a night, a male anaconda encounters Bill's pet monkey Kong and attacks him, but the monkey manages to escape. The following day, an anaconda attacks the team and kills Ben. Later, another snake also attacks Bill's friend John Livingston on his boat and devours him.

The remaining team members arrive to a nearby deserted village, but there an anaconda devours alive Gordon, who has been paralyzed by Jack with a poisonous spider shortly before. They then go into the jungle and are attacked by another anaconda, who manages to eat Tran underwater before being killed by Sam. A second one appears soon after and captures Cole, but Bill successfully kills the snake with his knife.

The team later finds the blood orchids above the pit where the male anacondas are mating with the female. Jack obliges Sam to retrieve the orchids, but after she did it the backpack containing the orchids falls into the pit and Jack is paralysed by his spider while trying to seize it, causing him to fall into the pit and be devoured by the snakes. However, the female anaconda then attacks them, but Gail tricks her into biting a fuel container and Cole shoots it with a flare, causing a chain reaction that kills all the anacondas.
