I'm not inside my skin. I am my skin.

They have nerves throughout their shells and can feel even gentle touch.

Yeah? Then explain this, mister '''''''scientist'''''''

So my head is not "inside" my skull but *is* my skull? Is the brain not a part of my head?

Idk I see a big cavity that would contain turtle...

I feel like an annual reminder would be entirely sufficient, to be honest.

Also, please do not move turtles unless they are immediately in danger or in your way. They're probably fine and just goofing around (laying eggs, moving, or looking for food).

That's tortoise silly billy

Domed, exoskeleton, this is a beetle.

who should i trust? Nintendo or a random person on the Internet?

Please don't tap/knock on turtle shells. It would be like someone knocking directly on your bones.

That's neat and all. But how do they retract their heads?

They can feel touch through their shells

What about Ninja Turtles?
