Biologic evolution

It is a photograph newly taken.
The photograph newly taken is the one having taken it from the direction of
mussel's hinge.
The word hinge was used because there dared to be no alias though there was
no hinge.
Perhaps, I think that it is a part of mussel's head.
This part opens though tends to think that the shell is not opened and shut
because the shell has stuck.
When the shell was wrenched open, the hole that the water pipe passed was
open.

It is straight from the position of the water pipe to the hole.


It is a photograph contributed before.
It is what taken from the hips part of the mussel.




One cave is made in the shell.



The action of the mussel was able to be understood from this.
It was a mistake though thought that the water pipe had gone out of
the hips part.
