Dolphins only sleep using half of their brain at a time, so they will still be above water and conscious of what they are doing when half of their brain is asleep, so they will still be breathing
Dolphins have a interesting way of sleeping
Yes they do!
Yes they do. They swim while sleeping though.
Dolphins actually have to surface to get oxygen from the air. Tuna and squid have special lungs called "gills" that allow them to remove oxygen directly from water.
Dolphins breath Oxygen, because they think about every breath they take.
They Breathe, with lungs, through a blowhole, like all other Dolphins.
No, the exact opposite is true. Plants expel oxygen, so sleeping in a room with plants is healthier for you.
They're not different. All dolphins (and whales for that matter) have half their brain sleeping and half their brain awake at all times. This is so they can go to the surface to breath and are not caught off guard by predators.
Dolphins jump out of the water because they ar looking where they ar or they ar avoiding the preditors
Dolphins breathe through the 'blow hole' in the top of their heads, surfacing from underwater to blow out the Carbon Dioxide and draw in oxygen.
By swimming to the surface - like dolphins do! :)
Yes they are. Is that your question?
