How do a clam eat?

A clam gets its food from the water.  Food enters by way of the clam’s siphon or “neck.”

A clam is an animal whose soft body is protected by two hard shells that close over it like the covers of a book.  There are many kinds of clams, in many parts of the world.  Some clams lives on the bottoms of oceans, others live on the muddy bottoms of lakes and streams.

Clams called soft-shell clams live buried in the sand along seashores.  They are sometimes called “longneck” clams since they have a long siphon which people call a “neck.”

When the tide covers the sand the soft-shell clam opens up its shell and pushes its long siphon up through the sand to the water above.  It sucks water into its body and digests the tiny plants and other food particles it finds in the water.

When the tidies out, the clam pulls in its siphon.  This causes a little spurt of water which shows someone who is hunting clams where the clam is hidden.

How are oysters born?

Oyster

Oyster are hatched from eggs.  An oyster spends all except the first few weeks of its life fastened to a rock or other hard object in the water.  Along the world’s seashores there are many kinds of sea animals with shells to rocks and other hard objects in shallow water near the shore.

A baby oyster is hatched from an egg laid by the mother oyster.  When first hatched, the baby oyster is about the size of a pinpoint and has no shell.  Its shell begins to form when it is a day old.  The baby oyster spends the first two weeks of its life swimming about freely.

Then it fastened itself so something hard, perhaps a rock or the piling of a wharf, or even to the shell of another oyster.  It remains fastened to the same spot for the rest of its life, feeding on tiny plants and animals carried to it by the current.

The oyster grows about an inch a mouth until fully grown.  Oysters are one of the most popular foods that we take from the sea. – Dick Rogers
