A sandy beach is made up of minute grains of sand or crushed shells and rock. Because it is grainy, wind and water reshape a beach every day. Sandy shores are exciting places with life in and underneath the water.
Walking Along a Sandy Shore
Always wear shoes when you walk along the beach. Besides the many natural items you find as you walk, unfortunately you'll encounter the man made dangers of broken glass, litter, and pollution, too.
Look for sea stars. Sea stars are a very basic and primitive form of life. If a sea star loses a leg, it will grow back. Obviously, such is not the case with a human being or a mammal. Through thousands of years, mammals have evolved to much more complex systems than starfish. Mammals' limbs are more complex, and have a central nervous system.
You'll find many sea shells. They are the former homes of snails and other aquatic creatures. Their exoskelton (which means skeleton outside the body) is all that remains of them. Shells are beautiful and fun to collect.
Clam shells are exoskeltons of living creatures. In parts of the world,
such as the eastern coast of the United States, you can dig for clams along
the beach and then cook them.
