The shell of a turtle is what sets it apart from every other animal.

No, all existing turtle species have a type of shell. So at the moment there are no turtles without shells, but this was not always the case. At the moment, the shells of Turtle Without Shell Picture turtles can easily be put in two very different groups, soft shells and hard shells.
The shell is made out of two main parts, and two secondary parts. The man parts are called the carapace and plastron. As you can see in this picture the carapace is the upper part of the shell, the part that covers the back of the turtle, and the plastron is the posterior part of the turtle.
The backbone is fused with the rest of the carapace, but a significant part of it can still be distinguished from the rest of the bones, unlike the ribs that have fused completely. Turtles are the only animals in the world that have all of their ribs fused into one big piece, every other animal has multiple ribs that are separated from each other.
Even if the shell has a different shape. The plastron is made up of nine bones and the two epiplastra. Here is a list of with the names of each bone:. At the moment the evolution of the plastron is a mystery. In the case of Turtle Without Shell Picture carapace we know that it was formed due to the fusion of the ribs and Bikini Ö backbone.
But when it comes to the plastroon there is no sure answer. The carapace and the platoon are the main parts that compose the shell, but the shell has two other important parts, one that connects the carapace and the plastron, and one that protects the carapace.
The bridge is the part that connects the carapace and the plastron, and it can be found on the sides of a turtle. The origins of the bridge are also unknown. The bridge has two roles, to protect the sides of the turtle, and to keep the carapace and the plastron fused. Turtles with a hard shell have something called scutes that make their shells harder than the rest. Scutes are made out of keratin. Keratin is the same thing that our nails are made out of.
Scutes act as a layer of protection for carapace. So if an animal bites them, the scutes will get damaged instead of the carapace.

Some of the oldest fossils have Turtle Without Shell Picture that the first turtles that were getting close to how modern turtles look, only had the plastron, and no carapace.

In scientists have come out with a theory that tells us why turtles have evolved to have a shell. Some of the oldest turtle fossils suggest that turtles were not living in the water, instead they were land animals that liked to burrow.
The theory suggests that the wider ribs would provide a lot of stability for the ancient turtles as they were digging. Similar wide ribs can also be observed in other animals that like to dig burrows, the ant eater for example.
The problem with wide ribs is that they greatly reduce mobility. As a result turtles are not able to move to fast. At this point the ribs started to fuse together forming the shell as we know it.
