What is the difference between a jellyfish and starfish?

Answer 1

Jellyfish are cnidaria coming from the greek "cnidos" meaning nettle. Sea stars are NOT crustaceans as the previous individual wrote, but are in fact echinoderms meaning spiny skin. There are many differences between these two phyla. For example, jellyfish are mostly pelagic whereas sea stars are bethic sticking to substrate. Jellyfish move by squeezing their bodies (bell) and forcing water out the bottom. However, they are subject to currents and winds. Sea stars in contrast move via many tiny tube feet on the oral surface (bottom of this animal). These are only a few examples.
