Biologic evolution

Skinning it in the shell put it on the photograph ..certain.. many times.
The shell of Hamagri was examined today.
It is understood only that the luster of the shell changes though Hamagri doesn't understand
there is a skin on man's eyes.



It is thought that it is possible to have done when faced with something, and the
luster of the shell has changed due to wound as shown in the photograph.
Is there a skin in the shell of Hamagri?
It thought whether it was not easy to understand because it stuck to the shell in case of being.


And, it took a picture with the microscope today.
How?
Do you say the skin to the shell?
I will already think for a moment.
