Edwardsia elegans is a tube-dwelling sea anemone (family Edwardsiidae) found in soft sediments along the Atlantic coast of North America, lacking a pedal disc and instead creating a mucous tube anchored in soft sediment with only the tentacle-bearing oral disc extending into the water column for feeding. The species is studied in the context of cnidarian phylogenetics as a member of one of the most basal actiniarian families, providing insights into early sea anemone evolution and body plan origins. Genomic data have been generated for this species and are available in public databases, enabling comparative studies of cnidarian evolution and ecology.
