Bryozoans are suspension feeders, dependent for their food on extracting edible particles from the water currents surrounding them. Most bryozoans are also sessile, unable to move from the place where the larva attached (except by that slow “movement” over the substratum that occurs by growth and decay of portions of the colony).
