<human>:  What is the difference between a jellyfish and a sea anemone?
<bot>: The main difference between a jellyfish and a sea anemone is that jellyfish are free-swimming creatures while sea anemones are sessile creatures that are rooted in one place. Jellyfish move by contracting and expanding their bell-shaped bodies while sea anemones have a firm base to which their tentacles are attached and they move by extending and retracting their tentacles. In terms of appearance, jellyfish have a clear, jelly-like bell-shaped body while sea anemones have a body that looks more like a flower.
