Biologic evolution

The prawn that did not have seen what was found today.
I think finding to be what entered by mistake from among in the case
of with various marine products.
It has not seen in Tokyo Bay.
The hermit crab and the crab have seen in Tokyo Bay.
The prawn has not seen.
The prawn like the photograph has not seen though the river prawn
thrown from the river that flows toward Tokyo Bay has seen.
It was not found though prawn's name was examined in shellfish's book.

Because prawn's skin was soft, did you just slough off old skin?
