What Is A Tortoise Shell Made of?
The composition of a tortoiseshell is simple. And they cannot leave their shell. It’s made of two parts. Carapace and Plastron. Let’s take a look at the composition of a tortoiseshell in detail:
The carapace is the back part of the tortoise. This part is made of ribs and broads. The interior portion of the carapace connects the backbone with the ribs and broads. It means their spine and outer part are connected and can’t get apart.
So, now you know why I told you previously that they cannot leave their shell. The carapace is not just a shell. Besides having many benefits of a carapace for the tortoise, it works as a protector, which saves the tortoise from predators.
The scutes work as a cover for the tortoise shell. It is a leathery skin that is made of keratin. The keratin has rich amino acids inside it. It also works as a protector of the carapace. But the scutes color in the carapace side and the plastron side have different colors.
The carapace side has bold color scutes and the plastron side has no mottling like the carapace side.
The plastron is the bottom side of the tortoise shell. But how this part of the shell is made is still unknown. People have made their theory about the plastron. Many believe that the sternum of the tortoise has developed it. But this theory is not a proven fact.
The Bridge Of Tortoise Shell
The tortoise shell’s bridge makes a joint between the carapace and the plastron. It is said that the bridge of the tortoise shell is also made from fused ribs. The bridge of the tortoiseshell has a few benefits. It protects the shell of the tortoise and keeps both parts combined.
The Conservation And Trade Of Tortoise Shell
Understanding the trade of tortoise shells helps us know the effect of trade on the world’s tortoise population. In ancient times, the demand for tortoiseshell was too much.
People used to make combs, brushes, and ornaments with the shell of tortoises. As the trade of tortoise shells was successful, the hawkbills were a significant threat.
Many hawkbills were killed to take the tortoise shell and make different things with it. In the 20th century, Japan was introduced as the world’s largest market for tortoise shells.
But later, the trade of tortoiseshell was banned. But Japan kept importing the tortoiseshell due to the demand of customers. Later, the county also stopped its trading. Still, some people trade tortoise shells illegally. But the trade of the tortoise shell is comparatively reduced a lot now.
