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.

What are mollusks?

Mollusks

If you have ever collected shells at the seashore, probably most of the shells you found were once the homes of living animal called mollusks.

The most familiar mollusks are probably clams, oysters, octopuses, squids, snails and slugs.

Most mollusks are related, or alike, in certain ways.  Mollusks are soft-bodied animals without bones.

Most kinds of mollusks, including clams and oysters, have hard shells that protect their soft bodies.

Other kinds, such as cuttlefish and squids, have no shells that show.  A special shell grows inside their bodies.

Octopuses and some slugs have no shell at all.

Mollusks live in most parts of the world.  Some, such as snails and slugs, live on land.  Others are found in rivers, lakes and ponds.  But the greatest number of mollusks are ocean dwellers.

Mollusks furnish us with food.  Their shells are made into many products, including buttons and jewelry.  – Dick Rogers
