The bristly tufts of the Nereidans and their allies are useful to them in various ways; they serve them in part as instruments of attack and defence, the bristles being usually sharp, and sometimes barbed at their extremities, so as to attach themselves with force to soft substances; they assist, also, in their movements over solid surfaces, taking hold., as it were, of the rock on which the animal is crawling, so that the hinder part of the body is prevented from slipping back, when the anterior part is pushed forwards; and they also aid in its movements through the 296 GENERAL CHARACTERS OP ANNELIDA. water, serving in some degree as oars by which it is propelled. In some instances, indeed, we find the tufts replaced by flattened plates, which are specially adapted for this last purpose. Where there are no locomotive appendages, the extremities of the body are usually furnished with suckers, which give important assistance in locomotion, --as in the well-known Leech. But in one tribe of this class, the animal, in its adult form at least, enjoys very little power of locomotion, being confined within a shell, which it constructs for itself, and which is attached to some solid support. 906.
