Class Asteroidea is most likely the "stereotypical example" of any echinodermata classes. If you could not guess by the picture at the left, Asteroidea is the class containing starfish (like Patrick Star!). Starfish are one of the greatest examples of echinodermata because:
a) they are obviously radially symmetric (just look at their arms)
b) they show a good example of how the water circulatory system works (by observing how they move around)
and
c) they are pretty to look at and easy to remember!
Starfish posses every trait that is generally looked for in an echinoderm. They are radially symmetric, they have a water circulatory system, they have tube feet for movement, they regenerate limbs, and so much more. The starfish in class Asteroidea are a prime example of echinodermata and they may be one of the most important classes (Invertebrates).
