Biologic evolution

It is a hinge of AOYAGI.

"TUBUGAI" and AOYAGI are the same shape.

TUBUGAI and the green willow have a similar point.

There is no null in the shell.

The shape of the shell looks like well, too and the shell is a thin point.

The point that the surface of the shell like the littleneck clam is not uneven
is the same.

The point without weight either is the same.

The point to live on sands looks like from the littleneck clam, too.




The photograph of the internal organs film of AOYAGI is taken.

This was the same as the littleneck clam.

It is two layer two piece shellfish type.
