03 – The Shells Are Securely Attached to Their Bodies
You can overlook each one of those kid’s shows you saw as a child where a turtle bounces exposed out of its shell, at that point plunges back in when compromised. The truth of the matter is that the shell, or carapace, is safely connected to its body. The inward layer of the shell is associated with the remainder of the turtle’s skeleton by different ribs and vertebrae. The shells of most turtles and tortoises are made out of “scutes,” or hard layers of keratin — a similar protein as in human fingernails. The special cases are delicate shelled turtles and leatherbacks, the carapaces of which are secured with tough skin. For what reason did turtles and tortoises advance shells in any case? Plainly, shells created as a methods for protection against predators. Indeed, even a destitute shark would mull over breaking its teeth on the carapace of a Galapagos tortoise!
04 – They Have Bird-Like Beaks, No Teeth
You may think turtles and winged creatures are as various as any two creatures can be, yet truth be told, these two vertebrate families share a critical normal characteristic: they’re furnished with mouths, and they totally need teeth. The snouts of meat-eating turtles are sharp and furrowed. They can do genuine harm to the hand of an unwary human, while the bills of herbivorous turtles and tortoises have serrated edges perfect for cutting stringy plants. Contrasted with different reptiles, the nibbles of turtles and tortoises are moderately feeble. In any case, the crocodile snapping turtle can eat down on its prey with a power of more than 300 pounds for each square inch, about equivalent to a grown-up human male. How about we keep things in context, notwithstanding: the nibble power of a saltwater crocodile measures more than 4,000 pounds for every square inch!
