==Description==
Ivell's sea anemone is a tiny, worm-like anemone up to long and diameter; the column is similar to other ''Edwardsia'' spp. There are twelve transparent tentacles, arranged in two cycles, nine tentacles in the outer cycle and three in the inner cycle. In life the tentacles of the outer cycle are held flat on the substrate, the three of the inner cycle more or less vertical, often curled over the mouth. Each tentacle has a few transverse bars of pale cream occasionally forming complete rings.
