Most interesting snake?

[DragonsEye]

Note, not necessarily the most beautiful. Like so many organisms, snakes as a group have developed a number of different adaptations for succeeding in their enviroment. Just curious as to what one or ones, folks here might have found to be the most intriguing and why. (The snake(s) in question do not have to be ones you own or have owned in the past.)

I think for myself, the stiletto snakes would have to be near the top if not at the top of my list of the most intriguing/fascinating adaptations. The jaw modifications they have undergone which allow them to envenomate prey without needing to do more than open their mouths to a slit as well as their entire venom apparatus are, IMO, just remarkable.

And a strike/feeding video that shows the ... awkwardness? ... such snakes have in swallowing their prey as a result of the adaptation of side striking.
