Fish have nostrils called nares which are
located on the snout above their mouths
. Under the skin just below the nare openings are small sacs which contain smell receptors. Water, carrying scent, moves through the sacs. The sacs are connected to the brain by nerves, allowing the fish to smell.

What is a fish's best sense?

What is a fish's primary sense?
Fish need to pick up on the smallest changes in their environment, so many of the adaptations help fish to sense the world around them. Their
eyes, nares, and specialized lateral line organ
are their primary sensory organs.
Where are the sensory organs located?
The human head
is home to all the body's major sensory organs, and the most important of these is the brain.
