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, box turtles cannot breathe underwater. They are terrestrial animals and must come to the surface to breathe air. They do not have the adaptations to extract oxygen from water like aquatic turtles do.
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.
No, red ear sliders cannot live in salt water. Not only can they not handle the heavy salts, it would very soon be food for some large fish or bird
Box turtles are primarily terrestrial and are not adapted for prolonged periods underwater. While they can hold their breath and may swim short distances if necessary, they typically cannot survive submerged for long. Extended exposure to water can lead to drowning or other health issues, such as respiratory problems. It's best to keep box turtles in a dry environment with access to shallow water for hydration.
On average, a common loon can hold its breath for about 50 second. They can, however, dive much longer if needed.
