About this species

Notophyllum foliosum is a species of annelid in the family Phyllodocidae. Roughly 12 millimeters long, the annelid is bristly and covered in scale-like cirri. The species is found in shallow areas of the seafloor of the Mediterranean, Scandinavia, and Madeira. It was originally described as Phyllodoce foliosa in 1835 and was moved to the genus Notophyllum in 1923. The species was split in two in 2010, with the deeper-dwelling Notophyllum crypticum being designated its own species.
