haha. I was gonna be the first one to guess and take a stab at albino cobra as well. :shakes head at self:
I came to the conclusion by:
1. Obviously with the red lid and rattler in the background, one would automatically think "hot". Especially if they've been to a reptile show that has hots. IMO.
2. Not a rattler or viper judging by size, head shape, and look of a kingsnake.
3. If you look close enough, there is a bit of "extra" at the bottom near the head squeezed against the container.
