Can tortoises and turtles change shells?
Every tortoise and turtle has only one shell that they get from birth. Since they cannot leave their armors, they cannot change to get a new one. The only exception is that some turtles can shed old scutes and form new ones. The one they have when they hatch gradually grows, and as new scutes develop, they overlap with the old ones.
Why do baby turtles have soft shells?

How do turtles and tortoises differ?
The Difference Between Tortoises and Turtles 1 Turtles live mainly in and around water, spending little time on shore. Tortoises are only land dwellers and can’t swim well, if at all. 2 Though turtles live primarily in the water, female turtles will come to land to lay their eggs and then return to the sea. The female tortoise may actually stay with her young until they are roughly 8 months old after hatching. 3 Turtles often have a smoother shell than tortoises so they can slip through the water with ease. Tortoises have large rounded shells that are very heavy which are necessary for protection against land and aerial predators. 4 Tortoises have stompy almost elephant-like legs and thick claws for digging. Turtles have slimmer legs and some even have flippers. If they don’t have flippers, turtles will have webbed feet used for swimming. 5 Tortoises walk on their toes; this is called digitigrade. If they have feet instead of flippers, turtles will walk flat on their feet. This is called plantigrade. 6 Tortoises are covered in thicker scales, especially along the outer edges of their legs, some will grow spur like scales which are useful to keep predators away. The scales of a turtle are smoother. 7 Most Tortoises will have a more earthy or dusty coloration to them, this is to help in their camouflage on land, but these colors vary depending on species and breeding. Turtles tend to be more colorful and have a wider variation of colors.
How to tell if a tortoise is dehydrated?
A tortoise’s skin is usually quite wrinkled and dry-feeling. That can make it tough to tell if your tortoise is dehydrated. On that wrinkled skin are sections of hardened scales with a slight bumpy texture. Most tortoises are in shades of brown and gray, but they can have some variations due to breeding in captivity.
How many vertebrae does a tortoise have?

How many bones are in a turtle's shell?
Because the shell is a turtle’s body, or rather its inside out skeleton. Peek inside (or use x-ray vision) and you will see that the shell consists of 60 bones made out of the ribcage, the backbone, the vertebrae, and the breastbone. Consequently, unlike snakes or crustaceans who perform shedding, turtles do not abandon their shells but instead grow with them. These shells not only protect them from predators but also from abrasion injuries. A turtle’s shell is separated into three: its dorsal (upper piece) is called the carapace, the ventral (bottom piece) is known as the plastron, and finally, a bridge that merges the two parts together.
What are turtles' ancestors?
Turtles come from the family of lizard and snakes and have since evolved into ancestors named Pappochelys and Eunotosaurus. The former are known for their buoyant bones and the latter for their digging abilities. Far from the turtles we know today, the ribs of these ancestors had slowly broadened and united, growing over the shoulder blades to create shells that are attached with the turtle’s skeleton. As mentioned, broadened ribs hinder breathing by ventilation and to an extent has a negative effect on locomotion, but all these changes were needed for the survival of our present-day turtles. There has been evidence suggesting how the sturdy-handed Eunotosaurus were essentially skilled in burrowing. Fast forward millions of years and we have the descendants, the turtles now no longer using their shells as a means for digging, but rather for protection, a classic case of exaptation and convergent evolution.
Why do tortoises have shells?
Tortoise shells are mostly used for protection and self-defense. Predators have a hard time getting their jaws around large, spherical shells. They also have great difficulty in chewing or scratching through these thick layers.

How many bones does a tortoise have?
In total, an adult tortoise has 59 bones in its dermal layer, 40 of which are a part of the top of the shell.

These scutes grow in a tortoise, overlapping each other and getting thick as the tortoise ages.
What is the hinge on a box turtle?
For example, box turtles have a hinge that runs across the bottom of their shell. This can close from the front and back, completely enclosing the tortoise inside. Alternatively, hinge-back tortoises have a hinge running over the top of the shell. They can use this to close in their back legs for protection.
Why did the ribs of tortoises evolve?
Since these archaic species were unable to flee, their rib structure evolved into complete, armored shells to protect them. The nerve endings and delicate dermal plates of a tortoise would be vulnerable to infection and injuries if the shell were missing.
What is the plastron of a tortoise?
The plastron is the central section of the shell. A bridge connects the carapace and plastron, which is joined by a ligament that firmly ties the two sections together.
