The first name is derived from the situation of the gills or branchiae, arranged in tufts along the sides of the back; and the second from the fact that they lead a free life, being never confined in tubes. They burrow in the sand and under stones, moving by means of lateral unjointed appendages, provided with bristles. The mouth is on the under side of the head, which has eyes and unjointed feeders. The sexes are separate. The A. piscatorum of the English coasts is used as bait. (See Annelida.)
