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.
In sea turtles, hatchling sex is determined by incubation temperature. [8] In species in which eggs are laid then buried in sand, indentations in the sand can be a clue to imminent hatching. [ 9 ] In sea turtles, this usually occurs about 60 days after the laying of eggs, and often at night. [ 10 ]
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.

5) Female sea turtles lay their eggs. 6) When the season is over, female sea turtles return to feeding sites. 7) Baby sea turtles incubate for 60–80 days and hatch. 8) Newly hatched baby sea turtles emerge from nests and travel from the shore to the water. 9) Baby sea turtles mature in the ocean until they are ready to begin the cycle again.
Snapping turtles mate in the water, and then the female will climb up onto sandy shores to lay her eggs in a hole she has dug in the sand. She lays dozens of leathery eggs at once, then covers ...
Box turtles, desert tortoises and water turtles all require different types of water, according to the California Turtle and Tortoise Club. Box turtles should be outdoors and kept away from predators.
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]
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.
