Because their lungs are so large.
Whales are mammals, so yes they can breathe. As far as I know, they can just hold their breath a lot longer than humans can.
Because their lungs are so large.
Most of them can hold their breath for quite a long time, so they just come up above the water to breathe.
A whale is a large aquatic mammal. Whales breathe air through their blowhole, into their lungs (unlike fish who breathe using gills). So there is a difference between a whale and large fish.
No, they aren't a mammal like a whale or dolphin so they breathe using the oxygen in the water.
If you were swallowed by a whale, you would most likely be lodged in its throat. You would have no air, and neither would the whale, so, in time, you would both die. Why do you ask?
Yes and so does any under water mammal
Whales don't breath underwater.They hold their breath underwater instead.Whales are mammals like us.They have lungs like us so they need to breath air above the water like we do. A whale can hold it's breath for up to half an hour underwater and thats only because it's lungs are huge.Our lungs only partly fill with air.A whale uses it's blowhole to breathe in air and when you see water spurting from a whale blowhole thats just the water vapour from the whale's lungs and any water around the blowhole.they need oxygen like us.If we didn't get oxygen we will die.
Yes, whales can drown. Despite being marine mammals, they still need to breathe air, so if they are unable to reach the surface to breathe, they can drown. This can happen if a whale is entangled in fishing gear or stranded on land.
They do not need a respiratory system since their skin is thin enough that the body is oxygenated by diffusion. So since they don't breathe they can't hold their breath.
What do you think? A long 100 ft Blue whale or a 45ft long T-Rex? So yeah a Blue Whale
ASLAM ASKED - "MA'AM,WHY DOES A WHALE SPOUT:" MA'AM REPLIED -"A WHALE DOES NOT HAVE GILLS TO BREATHE.WHALES BREATHE THROUGH THEIR LUNGS.THEIR NOSTRILS ARE ON THEIR HEADS.WHEN A WHALE GOES UNDER WATER,THEIR NOSTRILS GET CLOSED BY LITTLE VALVES AND THE AIR PASSAGES ARE SHUT OFF FROM THE MOUTH SO THAT WATER DOES NOT GO INTO THE LUNGS. WHALES USUALLY RISE TO BREATHE OVER FIVE OR TEN MINUTES.BUT SOME TIMES THEY REMAIN UNDERWATER FOR THREE-QUARTERS OF AN HOUR! YOU WILL BE SURPRISED TO KNOW THAT SOME WHALES HAVE BEEN KNOWN TO DIVE 600 METRES DEEP !"
