What type of bones do turtles have?
The carapace and plastron each arose from two types of bone: dermal bones that form in the skin and endochondral bone (bone arising from cartilage) derived from the skeleton. Evolution has intricately linked these two types of bone to produce the shell of modern turtles.

A turtle's body is made up of two parts. The upper part is called the carapace (or, shell). The lower part is called the plastron (the underside of a turtle). These two parts link together, kind of like a puzzle, and form what are called bridges!

Do turtles have hands?
While most turtles have webbed feet, some, such as the pig-nosed turtle, have true flippers, with the digits being fused into paddles and the claws being relatively small. These species swim in the same way as sea turtles. Sea turtles are almost entirely aquatic and have flippers instead of feet.
What are five examples of vertebrates?
Let's take a tour of the five main vertebrate groups alive today: the fishes, amphibians, reptiles, birds, and mammals.
Is a Salamander a vertebrate or invertebrate?
Amphibians are small vertebrates that need water, or a moist environment, to survive. The species in this group include frogs, toads, salamanders, and newts. All can breathe and absorb water through their very thin skin. Amphibians also have special skin glands that produce useful proteins.
What are 5 types of vertebrates?
The phylum chordata (animals with backbones) is divided into five common classes: fish, amphibians, reptiles, mammals and birds. Show examples of these groups and explain the characteristics that make one different from another.
Do turtles have cartilage?
