Named after the terrestrial flower that is equally showy, the sea anemone comes in a rainbow of dazzling colors, pink being among the loveliest. The color of the sea anemone depends on where they call home. If their host is a coral or sponge, they tend toward vibrant. In a more drab environment like a rock, muted colors reign. But this creature that's related to coral and jellyfish is more than just a pretty flowery glob; the anemone has some surprising traits. For example, they are carnivorous, can live to be 50 years old, and some of them can grow as large as 6 feet in width.
