Lumbrineridae

Iris worms[1] (Lumbrineridae) are a family of polychaetes in the order Eunicida.

Iris worms (Lumbrineridae) are distributed worldwide[3] and are primarily found in the soft sediment of shallow intertidal waters, but sometimes live on rocky bottoms and in algal holdfasts.

[4] Lumbrineris flabellicola is unusual in the way that it forms grooves and membranous tubes in various ahermatypic corals.

[4] A few observations suggest that iris worm diets include carnivory on various invertebrates and questionable herbivory.

[5] Selective deposit feeding was described for Ninoe nigripes[6] and Lumbrineris cf.
