Facts About Turtles
1. Turtles cannot breathe in water, but they can hold their breath for several periods of time.
2. Adult sea turtles can weigh from 150 – 1000 pounds!
3. They are thought to have exceptional night vision due to the unusually large number of rod cells in their retinas.
4. They use their jaws to cut and chew food. Some turtles can live for more than a year without food. 5. They lay soft and leathery eggs. The eggs of largest species are of round shape while the eggs of other turtle species are elongated. They deposits their eggs in holes dug in sand or mud and incubate the eggs themselves. Some turtle lay their eggs on dry, sandy beaches. They lay 100-120 eggs in the nest and take about 2 months to incubate and their sex is determined by the temperature. Temperature determines whether an egg develops into a male or a female: a higher temperature causes a female, a lower temperature causes a male.
6. The baby turtles crawl fast to the water.
7. Turtles have been on the earth for more than 215 million years.
