turtle facts

Turtles are majestic creatures that come in all shapes and sizes. On the outside, they may seem to live a very simple and sedentary life, but when you take a closer look, you will find them to be truly enchanting creations. Check our quick rundown of fascinating turtle facts, and you will surely agree!

For example, do you know that the shell over a turtle’s body is made of its own rib cage and spine? It consists of about 50 bones. These bones come together to make a hard and strong protective cover for the turtle. This shell is with them from birth and grows with them until they get older, which means a turtle can never outgrow the size of its shell.

Do you also know that turtles are some of the oldest reptiles in the world? Some live as long as 150 years! How is that for a long and beautiful life? Most species of turtles can live both on land and in water. Their webbed feet or flippers help them thrive in aquatic environments.

Here’s yet another fun fact: sea turtles can breathe air and remain underwater for a long period of time. They can even sleep while submerged! The majority of sea turtles spend their entire lives at sea, only returning to lay eggs on nesting beaches. They are very agile and graceful swimmers due to their streamlined shells and huge paddle-shaped flippers. Sea turtles’ rear flippers are used as rudders to steer in the water.

After 45 or up to 70 days, hatchlings or baby turtles will begin to break out from the eggs using their “egg tooth,” or temporary tooth. Once they are out of the eggs, they will still stay in the nest for several days until they have the energy to swim in the water. Hatchlings usually get out of their nest during nighttime as there are fewer predators.

Turtles can sleep underwater.

Turtles need to rest or sleep just like other animals. In the nighttime, most turtles sleep underwater. They also sometimes sleep while floating on the surface. If a turtle can’t get into the water to sleep, it will look for a safe place like a hole, a pile of leaves, or mud. Turtles can also take naps at any time during the day.

Large sharks are the common predators of sea turtles.

Hatchlings and young turtles have several predators like fire ants, lizards, raccoons, foxes, wild pigs, birds, coyotes, and carnivorous fish. While an adult sea turtle has fewer predators, its most common predators are the most ferocious ones: killer whales and sharks. The tiger shark, in particular, often takes a bite on the turtle’s flippers and even on its shell and breaks it. Sharks savor the taste and the protein content of the turtles.
