With their perfectly shaped and attractively colored bodies, starfish are reminders of happy seaside vacations.
Starfish are the most generally viewed parts of the echinoderms; the spiny-skinned animals. All echinoderms have five-sided bodies, and this shape can be seen in many starfish. When grown-up, the body of a typical starfish is drawn out in five rays, or arms, radiating from a central point.
