i would answer it if i could but it doesnt really make much sense.what do you mean?
mammals cannot brathe in oxygen that is in water so they shut their noses when they are in water to prevent the intake of the oxygen which is dissolved in water
Yes they do.
Seals have the ability to close their nostrils when they are underwater.
Apart from the ability to close their nostrils, seals hold their breath pretty much like you and I - simply by not breathing.
No that is impossible, for a turtle doesn't even have nostrils.
walruses, seals, alligators, beavers, hippos also some turtles and dont forget the good old Australian crocodile.
They close their Nostrils (Nose) so they can spend longer time under water so they can catch Seals Or Fish
Same way you close your bum.
a giraffe's nostrils help them by when they close them they block out dirt and sand.
Seals are mammals. They Breathe air with lungs, through mouth and nostrils. And they have to Breathe while sleeping just like you and I.
nooo!
Camels have specialized muscles that allow them to close their nostrils. This is an adaptation that to prevents them from inhaling sand.
They don't breathe under water, certainly not like fish do. When they dive they hold their breath, just like whales and dolphins do when they dive. They close their nostrils as they dive to prevent water from coming into their lungs, just as whales/dolphins close their blow-holes before they dive or submerge themselves in the water.
Yes the seal has nostrils that can close and open if wanted.
