PHYLUM ANNELIDA

Phylum Annelida are truly coelomate animals with metameric segmentation. Capacious coelom and its divisions by septa into separate water tight compartments gives much greater control in the use of the hydrostatic skeleton so that changes in shape, shortening, lengthening or bending can be achieved in one segment without unduly influencing the adjacent segments.
