Turtles can rest or sleep underwater for several hours at a time, but submergence time is much shorter while diving for food or to escape predators. Breath-holding ability is affected by activity and stress, which is why turtles quickly drown in shrimp trawlers and other fishing gear. [112]
The annual death rate of adults is typically a few percent, but is much higher for young desert tortoises. Only 2–5% of hatchlings are estimated to reach maturity. Estimates of survival from hatching to 1 year of age for Mojave Desert tortoises range from 47 to 51%. Survival of Mojave Desert tortoises from 1 to 4 years of age is 71–89%. [8]
In the northern part of their range common snapping turtles do not breathe for more than six months because ice covers their hibernating site. These turtles can get oxygen by pushing their head out of the mud and allowing gas exchange to take place through the membranes of their mouth and throat. This is known as extrapulmonary respiration.

Turtles live anywhere from 10 years to 150 years, depending on the species. The average lifespan for aquatic turtles is around 40-50 years old.
Baby yellow-bellied sliders may be kept in a fairly small tank (20 to 40 gallons), but as they age, after about three years, they will require much more space. One adult may be housed in a 75 US gal (284 L) or larger aquarium. The turtles require enough water to turn around, with a depth of 16–18 in (41–46 cm) recommended.

The flatback sea turtle was originally described as Chelonia depressa in 1880 by American herpetologist Samuel Garman.The genus Natator (meaning "swimmer") was created in 1908 by Australian ichthyologist Allan Riverstone McCulloch, and in the same scientific paper he described what he thought to be a new species, Natator tessellatus, thereby creating a junior synonym.
These tortoises can weigh as much as 417 kg (919 lb) and can grow to be 1.3 m (4 ft 3 in) long. Giant tortoises originally made their way to islands from the mainland via oceanic dispersal. Tortoises are aided in such dispersal by their ability to float with their heads up and to survive for up to six months without food or fresh water. [3]
