Members of the Phyllodocidae are characterised by an eversible pharynx and leaf-like dorsal cirri. The head has a pair of antennae at the front, a pair of ventral palps and a single median antenna known as a "nuchal papilla". There is a pair of nuchal organs and there may or may not be a pair of eyes. The first two or three body segments may be part-fused and bear up to four pairs of tentacular cirri. The remaining body segments each bear leaf-like dorsal and ventral cirri, the dorsal ones being larger. The parapodia are uniramous or biramous, and chaetae are present on all but the first segment.[2]
