If the snake is poisonous then two heads mean twice the amount of venom being pumped into your body if both heads bite you. However, they dont produce more venom than other snakes because that gland is not located on the head, but yes, if both heads were to bite you that means four fangs and twice the venom.
Well I've never heard of, or seen a two headed snake. But I imagine it would be no more poisonous then any other snake of it species, however if a poisonous snake were to have two heads it could probably dispense more venom into it's prey by the mere fact that it could bite them twice at the same time.
Technically they would have to be venomous snakes.
Poison = cyanide, arsenic, other chemicals.
Venom = different foreign proteins that your body reacts badly too.
Not to be a know-it-all of anything. Sorry if I sound like a prick. XD
There is actually.. in Nature it has happened to many animals to be born with two heads some just often don't live very long
theres no such thing?!?....but if tere waz then YE!! =P
That would depend on the type of snake. =D
only if you get bit twice
