What if turtles don have shells
But if it helps people take better care of their pet tortoises, it was worth the nightmares. Keep a close eye on your pet tortoise. Feed her well and maintain her enclosure. Check her shell frequently for cracks or holes, and get her to the vet right away if you notice any changes. Caught early, a damaged shell may be mended. How do turtles get their shells? Turtles and tortoises are born with their shells. While they may be softer right after hatching, they quickly harden and gain better protection for the animal.
Their shells grow with them, getting bigger and stronger over time. How do turtles grow their shells? Turtles need adequate calcium to grow and maintain a healthy shell. They also need a variety of vitamins and minerals from their diets to keep the shell growing at the same pace as their body.
Turtles have either a leathery cover to their cartilage shells or they have scales, or scutes, made from keratin that cover their bony shells. Can turtles change their shells? All turtles and tortoises are born with one shell.
They do not shed the shell, though some turtles may shed old scutes as new ones form. Turtles and tortoises can never leave their shells, so they can never change to a new one. Skip to content Someone seeing a tortoise or turtle for the first time might come to an incorrect conclusion about its anatomy. Tortoise and turtle shells explained Can turtles and tortoises live without their shells? Sensitive shells feel pain If you broke your arm, a part of your skeleton, you would feel immense pain.
Can tortoises and turtles get out of their shell? Can tortoises and turtles survive a broken shell? Any injury like this can lead to major infections if left untreated.

Just like our bones they can break if there is too much pressure applied to them. And just like our bones they can heal, but up to a point. The plastron is the posterior part of the turtle. This part is usually flat, but at some turtle species it can be a little curve.
The plastron is made up of nine bones and the two epiplastra. Here is a list of the names of each bone:. At the moment the evolution of the plastron is a mystery. In the case of the carapace we know that it was formed due to the fusion of the ribs and the backbone.
But when it comes to the plastroon there is no sure answer. The most accepted theory was discovered in the 19th century by a French zoologist, who suggested that the plastron is developed by the sternum of the turtle. 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 plastron, and it can be found on the sides of a turtle. The origins of the bridge are also unknown. But most probably the bridge is also formed from fused ribs. The bridge has two roles, to protect the sides of the turtle, and to keep the carapace and the plastron fused.
The carapace of a turtle is covered with scutes. 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. Most turtles are going to shed their scutes and grow new ones. So if an animal bites them, the scutes will get damaged instead of the carapace. But not all turtles can shed their scutes.
Instead they will grow new ones on top of the ones that they already have. 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 modern turtles can easily be put in two very different groups, softshells, and hard shells. Both of them are similar in structure, but there is one crucial element that makes them so different.
Like all shells, hard shells cover almost the entire body of the turtle, leaving out only the extremities. 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 carapace is mostly made out of broad and flattened ribs that have fused together, along with parts of the backbone. 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. There are over different species of turtles, and all of them have a different shell shape, some of them have a rounder shell, some of them have a more pronounced dome shape, and some of them have almost flat shells, but all of them have the same bone structure on the inside. Even if the shell has a different shape.
The plastron is made up of nine bones and two epiplastra. Here is a list of the names of each bone:. At the moment the evolution of the plastron is a mystery. In the case of the carapace, we know that it was formed due to the fusion of the ribs and the backbone. But when it comes to the plastron there is no sure answer.
