What is olfaction?

Olfaction is the sense of smell.

Olfaction is a chemoreception that forms the sense of smell.

In most animals, olfaction occurs in the nose through holes called nostrils.

Some animals, such as snakes, have a vomeronasal organ located between the nose and mouth that is used to smell prey. Snakes stick out their tongue and then touch it to the vomeronasal organ.
