== Distribution and habitat == Iris worms (Lumbrineridae) are distributed worldwide and are primarily found in the soft sediment of shallow intertidal waters but sometimes live on rocky bottoms and in algal holdfasts. Lumbrineris flabellicola is unusual in the way that it forms grooves and membranous tubes in various ahermatypic corals.
