A clam will spray a stream of water when disturbed. Also, a clam will shut it's shell tightly when disturbed.
I am not sure how to get a clam to open naturally. The way I have known to open a clam is by hand.
just open up your sea map to the southwest corner then close the ds that's right shut it up tight as a clam in its shell then open it and wala the symbol is there

You have to go underwater which is left to Aphrodite and you have to find a clam. It opens and closes. Try to get the pearl (which is inside the clam) when the clam is open.
the mussel of the clam keeps the shell together. But they can open it if the want.
You can tell if a clam is alive by observing if its shell is tightly closed or slightly open. If the clam is alive, it will try to close its shell tight when handled. A dead clam will have a gaping, gaping, or broken shell.
Open
If it doesn't open when you steam it.
On the beach
