This is what is inside the shell of a turtle and ensures you will be very surprised

Want to know how attractive and interesting nature is? Please look inside a turtle shell.

Many people may not know, but turtles are a very strange species. Because they are one of the very few species of skeletons that are exposed outside the body - the turtle shell itself.

A turtle is an animal with a very strange body structure.

The shell of a turtle is like the ribs of our species. But not only that, it is their backbone and breastbone. And just like humans can't just pull out bones, you can't pull a turtle out of its shell. Just if it is possible, what is hidden inside it is guaranteed to surprise you.

What's inside the tortoise shell?

The shell of a turtle is like the ribs of our species.

First, turtles also have shoulder and hip bones, just like humans. They are just inside the shell!

According to Maria Wojakowski - a biologist who has studied turtles for more than 10 years, turtles are the only terrestrial animal with this feature. They are also among the rare animals on the planet that can breathe . anus , through an extremely specific respiratory system.

2 parts of the hip and shoulder bone of the turtle.

The lung of the tortoise is at the apical apex. In fact, the majority of terrestrial animals breathe by stretching their ribs, creating air thrust in or out of the lungs. But with turtles, they cannot do so because their ribs are fixed into shells. So instead, the tortoise will rely on the muscles inside the shell, to breathe and breathe oxygen through the mouth.

But they don't always breathe like that. At many times, turtles exhale through . the tailgate , through a unit called a "vent hole" (cloeca) . It is also the parts for turtles to perform . personal hygiene (urination, heavy walking) and laying eggs. In some cases, the vent also acts as a fish gill, drawing water in and absorbing oxygen there.

Turtles that breathe through the back holes often occur when they have to stay too long in the water.

Wojakowski explained that turtles breathe through the back hole often when they have to stay too long in the water. Roughly a state like hibernation.

That's still not the most interesting of the turtle shells. If you look closely, you will see a turtle shell has a folded structure - a special structure that allows them to store and release chemicals. As a result, they can even breathe without oxygen (of course for a limited time).

Turtle shells have a folding structure that allows them to store and release chemicals.

The process goes like this: many temperate turtles often go into hibernation when the lake freezes, causing the oxygen in the water to dry up. To survive, their metabolism must change, stop converting oxygen into energy, and start using glucose. This process is called "anaerobic respiration" , with a byproduct of lactic acid.

Theoretically, if the acid accumulates enough, it could kill the turtle. But this is the time when the folding structure of the tortoise shell works With this structure, tortoise shells absorb the lactic acid produced, while also producing an alkaline form to neutralize them. An apricot shell is too convenient, right?

The primary use of turtle shells today is to protect them from predators.

Wojakowski said that the turtle's shell has many other uses. In fact, science believes that tortoise shells were originally meant for digging - a product of evolution 200 million years ago. "They can dig tunnels with very complicated structures." - she shared.

And of course, the main use of turtle shells today is to protect them from predators. Almost no animal in the world can crack a turtle's shell, unless it has a powerful jaw (like a crocodile) or devises tactics such as stealing them up and dropping them down like an eagle.
