A python captured in Malaysia on Thursday is believed to be the largest snake ever captured.

The Telegraph reports it is eight metres long and weighs 550 pounds. If confirmed, the reticulated python would be 33 centimetres and 200 pounds larger than the current Guinness Book of World Records holder, the Missouri-based Medusa. Reticulated pythons are thought to be the world’s longest snakes.

The monstrous snake was discovered under a tree by workers at a construction site in Paya Terubong, on the island of Penang. It took members of the civil defence department half an hour to capture the reptile. It is currently being held at civil defence headquarters while awaiting a transfer to the state wildlife department.

Found in Southeast Asia, reticulated pythons are non-venomous constrictors. They are usually not a danger to humans, although they’ve got the strength to kill an adult male, and their jaws could open wide enough to swallow a teenager.

Even if its size is confirmed this new specimen will not be the largest snake ever found. In 1912, a snake shot on the island of Sulawesi in Indonesia measured 10 metres in length. Fossils of Titanoboa, a 12 metre-long relative of modern boa constrictors that lived about 60 million years ago, were found in Colombia in 2009.
