SEASHORE
TWO-SHELLED CREATURES
Common Mussels
Common Mussels are blue or brown
and found on rocky shores and
estuaries. They attach themselves
to rocks by thin threads. People
collect this kind of mussels to eat.
Razor Shell
Razor Shells look like old-fashioned
razor blades. The creature inside lives
buried in sand or mud, often as deep
as one meter. The two shells
are hinged of one end.
Heart Cockle
If you look at the side of this shell,
you will see a heart shape, which is
how it got its name. It lives in muddy
sand below the low tide level,
but may be washed ashore.
Virginia Oyster
The Virginia Oyster sticks firmly to rocks.
The shell often follows the shape of the
rock. It is found on the middle shore.
Scallop
Scallops move around by clapping their two
shells together, forcing water out behind them
to jet themselves along. There are several
hundred species of scallops.
