When arctic seals huff and puff, icy air and water molecules fly up their nares and into a labyrinth of nose bones called maxilloturbinates.

The eyes of those animals sit on top of their head, and their nares are likewise positioned high on the snout, which enables them to breathe air while looking above water.

“Nonsense,” said the swan snappily, putting its head into the water and giving them a frown with its black nares.

Curves for stool, buccal mucosa and anterior nares suggest that the proportion of gene-to-taxa discovery has stabilized.

But blood may proceed from the gums or throat, or may run back through the posterior nares from the nose, and then it gives alarm by seeming to proceed from the chest.
