Sharks have two nostrils (called nares) below their snout that are used for smelling, but they don’t join up to the back of the throat like our nose does, so they can’t sneeze like we do. If something floats into their nares, they might try to shake it out. Sharks breathe through the gills at the back of the mouth.
