Sand Dollars will be the topic of discussion on the all new Natures Wonders on Natures Talk Show. What are Sand Dollars? 
A sand dollar shell looks sort of like a round white coin, which is where it gets its name. When you see a sand dollar that's washed up on the beach, it usually appears to be a round, white circular disk, typically one inch to four inches in diameter. When they're alilve they're actually a dark color, covered with short dark spines that look almost like fur. These spines are moveable, and the sand dollar uses them both to move around on sea bottom and to push small pieces of food to its mouth.

Just as the common sea star or starfish has five arms, most sand dollars have a pattern of five sets of pores on them. Those are used to move sea water into the sand dollar's body, which is then pumped to where it's needed to aid in movement or other internal functions.
