Usually, the old, full-grown turtles have a carapace length of 16 to 26 inches and sometimes reach up to 30 inches in length. The turtle’s shell is made of calcium carbonate (CaCO 3 ), a mineral that is found in the shells of many animals, including humans.
The shell of a turtle is also made up of keratin, which is a protein-like substance that makes up the outer layer of the animal’s skin.

What is the average age of a snapping turtle?
The lifespan of snapping turtles is between 8 to 10 years and can go up to 40 years or more. Depending on the size of the home range, they typically occupy 4 to 22 acres.
The snapping turtle is the largest turtle in North America and the second largest in the world. The turtle’s shell is made of keratin, which is a tough, fibrous protein that is found in hair, nails, feathers, and other body parts.
Can you tell a turtles age by its shell?
To tell a turtle’s age, start by counting the number of rings inside one of the scales on the turtle’s shell. If you divide the number in half, you can get a general estimate of the turtle’s age. You can use the turtle’s shell color to estimate its age. Turtles can live up to 20 years, but the average life span of an adult turtle is about 10 years.
Can you tell a snapping turtles age by its size?
If you count the growth rings of young individuals, you can get a fairly accurate estimate of the animal’s age, but this method is less reliable with mature specimen.
It is possible to estimate the age of a turtle by counting the number of rings on its shell, since the turtle’s size and shell provide additional clues about its age. Turtles can live up to 20 years in the wild.
The average lifespan of an adult turtle is about 10 years, and the average length of life for a hatchling is 2 to 3 years.
What is the oldest snapping turtle ever recorded?
When the alligator snapping turtle named thunder passed away in 2010, it was thought to be 150 years old. “Thunder was the oldest turtle in the world at the time of his death, and he was a very well-preserved specimen,” said study co-author and Florida Museum of Natural History curator of vertebrate paleontology and paleoecology Dr. David Evans.
