The shell contains keratin and has ribs, and the spinal skeleton is fused to it. The carapace is the shell’s outer structure, comprising separate horny pieces called scutes to help shield the tortoise from injuries. The shell is primarily made of two parts the plastron and the carapace, forming a bridge. The shell also contains the dermal bone, which is infused into it to form the extended ribcage, now known as the hard shell. It comprises bones such as ribs and other skeletal structures, typical among reptiles. The tortoise and turtle’s shell is an intricate design of the reptiles’ exoskeleton. The tortoise scutes will, however, overlap and stay in place. Another different trait is that the turtles’ shells consist of scutes these parts will eventually start overlapping as the babies grow and will begin to shed. Like adults, baby turtle shells are flatter, leathery, and softer, while baby tortoises have rounder, thicker shells. The cover is also the exoskeleton, meaning that it must grow alongside other bones in the turtle’s body. ![]() It becomes an integral part of the turtle, and it’s impossible to detach it without hurting them in the process. The turtle grows with the same shell instead of growing a new one. Unlike the adult reptiles’ shells, the baby turtles have softer armors, which get harder as they mature. The baby turtle still needs protection hence, the shell is a vital organ. Are Tortoises and Turtles Born With Their Shells?Įvery turtle and tortoise species has a soft shell after hatching. Other tortoises and turtles also have extremely hard shells which makes it tasking for a predator to crush during an attack. All the efforts by a predator to remove it from the location will prove futile. These places are the most secure hiding spots given that once it settles among the rocks, its lungs inflate, tightening the shell. ![]() The shell is mostly dome-shaped, hard, and heavy for most tortoise species except for pancake species, whose shell is flattened, allowing it to survive by fitting in between rock crevices. Therefore, a tortoise’s shell is a bone structure to shield the internal organs. This armor is an evolved version of their ancestors’ hard ribs, which also served as protection. Contrary to many people’s beliefs, the shell is not just an outer detachable cover. Different species have various shell shapes and sizes to suit their needs and help them fit in their various habitats. Where the reptiles fail in speed, the hard shell doubles up to serve as protection. Primarily, the shell acts as armor for the tortoises and turtles to shield them from predatory attacks. These two parts have now evolved and joined to form what we know as the outer shell. ![]() It consists of the plastron and the carapace, both extensions of the reptiles’ skeleton. With countless years of evolution, tortoises and turtles have been famous for their rock-hard shells. 15 Parting Shot Why Do Tortoises and Turtles Have Shells?Īlthough there are various tortoise species distributed the world over, one thing remains constant their shell.
