pet turtles can sleep as much as they want in water if they loose oxygen they will lift their heads and get oxygen
My baby turtle sleep underwater. They need to be able to get on land and in fact they enjoy it! My turtles do fine out of water for an hr or more because they also sleep out of water. Turtles need time out of their terrarium so they can work out.
2 hours
Turtles can stay under water from one hour to five hours depending on the species, water temperature ect.
they can sleep up to 15 hours
Yes, sliders are one type of turtle capable of sleeping under water. They can last for surprisingly long amounts of time but will automatically wake up to rise for air when oxygen levels become low. Even though all are capable, some turtles will non the less choose to sleep with their bodies submerged in water with only their noses or full head out. I've even seen some turtles taking naps totally out of the water. So yes, red eared slider turtles can safely sleep under water if they so choose to.
Most species of turtles can survive out of water for a long time, as long as the environment is humid and out of direct sun. It is not a good idea for turtles to be completely removed from water, though.
They can sleep under water because they can hold their breath for a very long time.
Turtles have to go to the surface of water to breathe so if they get caught in underwater fishing nets they will drown.
They sleep for about 2 1/2 hours to 3 1/2 hours!!
Answer=========================================================Most aquatic turtles can pull oxygen out of the water, greatly increasing the amount of time they can stay under water. Big sea turtles can stay under for up to 2 hours, even sleeping while submerged.
Sea turtles can stay under water for almost their whole life! One of the only times they come out of the water is when they are going to lay there eggs because they lay there eggs on land and leave them and then the babies have to find there way back to sea all by themselves. Most of them get eaten by seagulls on their way so that's why there are not so many sea turtles... Most of them get eaten.
They're able to hold their breath for about 2 hours.
