same thing human nostrils do - direct air into the lungs !
Snakes have nostrils.
Through their nostrils !
Well, snakes have "nostrils" so they need a nose to come out of... :)
Snakes breath through the nostrils located in the head .
well anacondas breathe through there nostrils like other snakes.
Yes all boas and all other snakes have nostrils however the hole in the mouth for breathing while they are eatting is called the jacobsens organ
Snakes breath through nostrils like you and me, but if you mean how do they smell, then the snake's sense of smell is in it's tongue, which is why snakes flick their tongues a lot.
with their heat sensing system inbetween the snakes nostrils that is how they can hunt u down and kill u.
Same exact organs as you and me, but in a different package (snakes have one lung though, and snakes, monitors lizards, tegus, and some other lizards have a Jacobson's organ like cats, which allows for better smell, and directional smelling but the reptiles mentioned use their tongue for smell, and snakes have no nostrils).
Of course! Snakes have a much greater sense of smell than humans, in fact. Snakes do not have protruding noses(or ears, for that matter). They have two nostrils just above the mouth. Snakes also "taste" the air with their tongue. This could, possibly, be classified as another form of "smelling" by some people.
A horse has two nostrils.
frogs have nostrils inside of the mouth.
