Amphinomida is the name of a subordination of mobile or in tubes as predators or scavengers living polychaete (Polychaeta) in the order Aciculata and subclass Palpata , which are found in oceans around the world and the two families Amphinomidae and Euphrosinidae includes.


The amphinomida have an elongated or oval body that can be a few millimeters to 50 cm long. Well developed branched gills sit on the parapodia . This group is characterized by strong bristles with embedded calcium carbonate , which break off when touched, remain in the skin of the person being touched and cause inflammation. Thus, the amphinomida are protected from many predators. In addition, the group is characterized by a reduced prostomium , which is surrounded by the first segments. The peristomium is reduced to lips. The muscular pharynx has neither jaws nor teeth.

Distribution, habitat and way of life

The amphinomida are distributed in oceans worldwide from the intertidal zone to the deep sea, but they are particularly found in shallow warm waters. They move as active ground dwellers on sandy, muddy or rocky surfaces and feed on carrion or live prey , mostly sessile animals such as sponges or cnidarians , which are rasped off with their hard lower lip (peristomium).


The following two families are included in the subordination of Amphinomida :
