Easy, they don't.
A turtle needs air to breathe. Some turtles can slow their metabolism, allowing them to sleep underwater, but it must come up to the surface of the water in order to breathe. It can hold it's breath and stay underwater awhile, but it must surface to breathe or it will drown. Turtles cannot breathe underwater because they do not have gills, like fish - they have lungs, much like human lungs. Some aquatic turtles such as the red-eared slider can hold their breath for 3-4 hours, which might make you think that they are breathing underwater, but they really are not.
no. baby turtles must hatch on land because the cannot breath underwater like fish do. they have lungs like you and I.
no. they cannot. they do not have gills so therefore they cannot breath underwater.
No. They cannot breathe underwater. Turtles and tortoises are reptiles.
No. Human beings cannot breath underwater at all without an external source of air.
No. Monkeys are mammals, so they have lungs, which cannot filter water. They can hold their breath underwater, though.

A whale CAN drown- they cannot stay underwater indefinitely. When underwater, they hold their breath. They are REALLY good at holding their breath, and their bodies have adapted to doing that.
On average, a common loon can hold its breath for about 50 second. They can, however, dive much longer if needed.
no, that just silly!!!! No they do not breathe under water. They have lungs. Aquatic turtles such as the red - eared slider can hold their breath for 3 - 4 hours. If you are wondering because your turtle is blowing bubbles from behind it, it is because it is a sexually mature male turtle. A few species of turtles have cloacal bursae that are rich in blood vessels and can be used for gas exchange. The vast majority of turtle species do not either have these cloacal bursae, or if they do, they cannot use them for gas exchange. Please refer to the end of the article I am added to related links.
Dugongs are mammals, and mammals CANNOT BREATHE UNDERWATER, but they can hold their breath for a few minutes.
They swim in the sea and they lay their eggs on the beach
