Mainly water, as droplets and as moisture. There might be some mucus too.
All whales have blow holes to breathe, also to spurt out the water they suck in when eating plankton.
Whales have lungs and come to the surface to breathe. Their nostrils called blowholes are located on the top of the head to access air easily. Whales exhale, condensation from the 2 blowholes forms a 'v-shaped' 'blow'. when they submerge they hold their breath.
I'm pretty sure your talking about whales. Blow hole is the correct scientific term.
Humpback whales breathe air by using their lungs. They can only breathe in when their blowhole is above the surface of the water. When they exhale, you can see a spout of warm moist air shoot upwards from their blowhole.
A blowhole is what whales and dolphins use to breathe air.
it is called its blowhole
Whales breathe in and out of their blowhole. They are unable to breathe through their mouth because the trachea is not attached to the throat.
Usually whales. Most fish don't have a blowhole because they have gills. Only mammals such as dolphins and whales have blowholes.
The blowhole is the whale's "nose." Whales breath through them.
Whales, dolphins and porpoises have a blowhole, (or nostrils), on top of their head so they can breathe in and out when they are on the surface of the water. Since they are the only mammals that spend their entire lives in the water, and much of it underneath the surface, they are the only mammals to have a blowhole on top of their head. Most mammals have their nostrils in the front of their face, similar to human beings.
Whales use a blow-hole to take a breath when they come from under water because their mouth is not connected to their lungs like other mammals. They are not mouth breathers. They don't choke on food either.
