Indeed.
I'll admit I do like to mess with some people sometimes when they come into the store and ask if any of our snakes are poisonous. I'll loudly proclaim that there isn't a poisonous snake on this planet...and then I'll explain the difference of something being venomous or poisonous.
True, they're often viewed as being synonymous, but I like being a stickler to the details.
Just like snakes "dislocate their jaws" to swallow big prey items.
