You can see that the covering of the eyes also comes off. Isn't that amazing.
While looking to try to identify this which I didn't by the way. I went off in another directions. I found some interesting ways to tell if it is a poisonous snake or not. There are a few distinguishing characteristics that help us in this. Poisonous snakes have vertically elliptical eye pupil. If it is a pit viper it has an opening between the eye and the nostril which is called a pit. Non-poisonous snakes don't have that pit and their eyes are round.
Another interesting way to tell them apart that I didn't know is their tails. Poisonous snakes have a single row of scales under their tails. Basically they are circles around the tail. The nonpoisonous snakes have divided scales that appear to be in two rows.
I think I'll look at their eyes first before checking out their tails if I come across a live snake, don't you think?
