How do blue whales spray water out of their bodies?

Answer 1

They don't blow water as such, they blow air. But because its done at the surface in the wash of the waves, a lot of water is picked up and sprayed in the air.

The blowhole is the nostril of the whale and has a tight valve to keep water out. If they inhaled significant amounts of water through the blowhole, its possible that they might drown

Answer 2

They don't.

Instead of nostrils like most mammals have, they have an opening on their back called a "blowhole". They use this to breathe through. When they spout, they're basically just breathing out really hard. So it's not really "spitting"; for one thing, it doesn't come from their mouths but from their equivalent of a nose.

It's also not water... or, rather, it is water, but it's mostly the water contained in their warm breath as water vapor condensing as it hits the cooler air outside their body (you may have noticed that in the fall or winter, sometimes you breathe out "smoke" or "steam"; a whale spouting is basically the same thing on a much larger scale because whales have enormous lung capacity).

Answer 3

A male whale gets excited when it sees a female and squrits water from its blow hole.

Answer 4

It is natural. It is equivalent to the nose of the whale. Whales breathe through their blow hole.

Answer 5

A whale squirts water vapor from the blowhole. It fills its lungs with air before going under water and the air gets warmed in the lungs which is why it comes out as water vapor.

Answer 6

The same as a human blows their nose.
