Is There a Biggest Snake?
Snakes are thought to have evolved from lizards, with the first fossils
appearing between 143 and 167 million years ago.
After the dinosaurs died out 66 million years ago, modern snakes evolved.
There are now over 3,000 snake species worldwide, 600 of which are venomous.
They are one of the most lethal animals. The WHO estimates that snake
bites kill between 80,000 and 138,000 people annually.
Snakes are found all over the world except in Antarctica, Iceland, Ireland, Greenland, and New Zealand.
Snakes vary greatly in size, with the smallest measuring only four inches. Worst case scenario.
According to Graham Alexander, snake length estimates should be taken "with a grain of salt."
