Biologic evolution

The Tsmeta shellfish seems to puncture hunting and clam's shells, and to eat
the part of contents.

It is exterminated as a shellfish that gives harm though it becomes an ingredient
for that.

The shell how is punctured, and has not been seen by me.

It is yesterday's continuation today.

The Tsmeta shellfish doesn't have secretion liquid "Null" in the shell.

It hunts, and the ark shell, the clam, and Nishisazae have "Null" in the shell.


It understands from the sense of the finger when touching.

The Tsmeta shellfish doesn't have it.

In the part of Tsmeta shellfish's foot, there is "Null".

However, there is no "Null" in the shell.

It is thought that the shell corrodes with seawater if there is no "Null".

It is not convincing that there is no "Null" in Tsmeta shellfish's shell.

The Tsmeta shellfish is put in the bucket and the action is observed today.

Then,

A mysterious action is found in the action of the Tsmeta shellfish.



Tsmeta shellfish's foot encompasses the shell.

When this is seen, the shell might be able to be defended from seawater if it
is this body pose.




Though the part of the shell has gone out a little

If it is a deep sea, all the shells might be wrapped.

Even if the shell is put out to seawater until how much time, will it be safe?

It is a new doubt now.

Is the time of the filling pull of the tide related, too?

It is a doubt.
