This huge snake is a native of Asia. This is the longest snake on Earth: The Reticulated Python. They may be the longest, but they're not the biggest and heaviest. That honor belongs to the green anaconda. These guys are obviously constrictors and that means they squeeze the life outta prey, then swallow it whole. Legend has it that these behemoths are capable of eating us humans, but I've not heard of a single case of a reticulated eating a human. Usually, a constrictor's pupils are round, but not the reticulated pythons. They may be slow, but they strike out hard and fast.
