Blue Crabs: A Messy Meal from the Chesapeake Bay
What have ten legs, two of them large claws, a hard shell cover, and live in oceans, fresh water, and on land? Crabs, of course!
There are thousands of different kinds of crabs all over the world. They can be as small as a few millimeters across or grow as big as 4 meters. And all play an important part in the environments in which they live.
Crabs may look strange. But many people also find them delicious. The blue crab is an especially popular crab for eating in the United States. These crabs can grow up to about 23 centimeters and they get their name from the blue coloring on the legs and claws.
