Angling Times (UK) - - UNDERWATER SPECIAL -

Four nares po­si­tioned in front of the eyes act in a sim­i­lar way to our nos­trils, ex­cept that be­cause water is so dense it flows through the nare rather than in and out. The nares are lined with scent cells which sam­ple the water as it passes over them and can de­tect minute quan­ti­ties of chem­i­cals dis­solved in the water.

As the nares are on the sides of the head and work in­de­pen­dently of one another, carp are able to de­ter­mine the di­rec­tion a smell is com­ing from.
