A comparatively simple body plan is found with a straight line arrangement of the visceral organs somewhat like that of the monoplacophoran gastropod neopilina galatheae mentioned earlier see shell classes. Usually they are also branched to several micro aesthetes. In most cases fertilization takes place either in the surrounding water or in the mantle cavity of the female.
