Through blow-holes on the top of their heads like all members of the whale family.
No whale sharks don't have blow holes they have gills like other sharks
Whales blow holes are similar to our noses. They allow the whale to breath by coming to the surface. Its basically like a nose on top of the whales head, and is evolved from a nose like ours.
the height of the blow of the Blue Whale is 10-12 meters high.
To breathe.
Sharks unlike whales breath through gills and do not have a blow hole scince they are adapted to go really deep down if a whale went really deep down it would not be able to come back up for air scince it would run out of time
