What is the longest snake in the world?
List of largest snakes
reticulated python
Although it is generally accepted that the reticulated python is the world's longest living snake, most length estimates longer than 6.35m (20ft 10in) have been called into question.[6] It has been suggested that confident length records for the largest snakes must be established from a dead body soon after death, or alternatively from a heavily sedated snake, using a steel tape and in the presence of witnesses, and must be published (and preferably recorded on video).[6] At least one reticulated python was measured under full anesthesia at 6.95m (22ft 10in), and somewhat less reliable scientific reports up to 10m (33ft) have appeared.[8]
