The world record for the largest snake in captivity is 48.8 feet or nearly 15 metres. This huge animal weights nearly half a ton. This Reticulated python was caught in Indonesia and is said to eat 3-4 dog’s per month, but could swallow something as big as a cow! 15 metres is about the same as 8-9 men lying down in a row! However amazingly this creature still weighs less than the worlds fattest man.
