Dolphins sleep with one hemisphere of their brain still active so that they can perform the life functions they need to perform such as surfacing to breathe.
they can sleep long with one eye open -they'll drown if both are closed also their eye is open to sense danger or they'll die.
There is no evidence to suggest that dolphins intentionally try to drown humans. Dolphins are generally known to be friendly and intelligent animals that do not pose a threat to humans.
Well, if they drown, yes, but not because of the dolphins
Dolphins breathe air, so if they get trapped underwater they will drown.
Dolphins sleep near the surface. They sleep in the water.
dolphin sleep in ocean and in hear share
When the sleep their brain is half awake so it can breathe
Dolphins are mammals, they Breathe air. If trapped underwater they eventually suffocate or drown.
Dolphins have tails to swim, manouvere and to jump, if they didn't have a tail they would drown, Hope that helps! =)
They sleep under water.
dolphins don't sleep when they get tiered the only thing they do is swim then come out of the water
there is no such thing as a pink dolphin. But if there was no it would not sleep. Normal dolphins don't.
