How do whales benefit from a nostril at the top of the head?
It doesn’t interfere with the eyesight of the whale.
A whale can emerge from the water, inhale and resubmerge without stopping or tilting its snout to breathe.
The whale doesn’t need to breathe air because it has gills like fish.
The whale can use the nostril to smell prey so that it will not starve.
