The oral disk has white stripes with small dark spots, radiating from the mouth. Body column plain, smooth with regular ridges along the length. Colours range from brown, purple, blue, yellow, green. The animal can retract rapidly and completely into the ground when disturbed.

Sometimes mistaken for a flowery soft coral (Family Nephtheidae). While the soft corals don't sting, fire anemones do!

Fiery Creature: The common name comes from its nasty sting, so please don't touch the Fire anemone!
