What is a clams mobility?
. The soft-shell clam digs a permanent burrow in which it remains for life unless disturbed. As it grows the clam enlarges and deepens its burrow.

When the tide goes out, the clam withdraws its "neck" and closes its shell until the tide comes in again.

How does a sea star feed on a clam?
It forces its stomach out, and sticks it inside of the clams shell. Then with the clam inside of the stomach, the starfish puts its stomach back on its inside. A sea star opens up a clam by attaching its hundreds of tube feet to the external surface of the shell with suction. Then, it pulls. It might have to pull for hours, or days, until the adductor muscle holding the shell firmly closed is finally weakened enough that the shell opens. Then the star fish can force its stomach in and digest the soft insides of the clam.

What does a natural pearl look like?
Yes. It happens when a clam gets 1 grain of sand in its mouth, then the grain of sand turns into a pearl (but I don't know how! Sorry!). Then someone goes clam fishing or finds the clam and opens it up to get the pearl. Not all pearls are white. And not all clams have pearls in their mouths.There is also a process called culturing where a small piece of clam shell is placed inside an oyster's shell. To protect itself from the irritation caused the oyster coats it with th stuff pearls are made of and a pearl is made. The longer the pearl stays in, years, the bigger it gets. Most of the pearls around today are cultured.Yes it does but it is not made by sand. It is actually made by a parasite entering the clam and the clam coats it with nacre. Nacre is what a pearl is made of. Not sand.
