This movement depends upon mainly on the contralateral waves of contraction of the longitudinal muscles of the body wall that causing lateral undulations of the body. The parapodial activity explained above supplements the body undulations. This results in rapid crawling. The crawlers involves polychaetes of many families such as nereids, syllids, phyllodocidae etc.
