Anatomy: Animals Inside

Skeletal System

What are the upper and lower shells of a turtle called?

Ants are incredibly strong in relation to their size—and they don’t even have a skeleton. They can carry objects ten to twenty times their own weight, with some ants able to carry objects up to fifty times their own weight. In fact, ants are able to carry objects over great distances and even climb trees while carrying such objects. In some cases, this is comparable to a 100-pound (90 kilogram) person picking up a small car, carrying it 7 to 8 miles (11 to 13 kilometers) on his back, then climbing the tallest mountain while still carrying the car!

The turtle (order Testudines) uses its shell as a protective device. The upper shell is called the dorsal carapace, and the lower shell is called the ventral plastron; the shell’s sections are referred to as the scutes. The carapace and the plastron are joined at the sides of the turtle.
