In an opposite direction they maydevelop a supplementarj- covering of dermalplates and a more rigid integument, whichindicate their nearer relationship with sea-urchins. The majority of sea-urchins and star-fishes pass through a series of interestingmetamorphoses before arriving at the adultstate. The larval phases in these instancesare free-swimming organisms, having arm-likeprocesses, strengthened by calcareous rodsthat have been likened in contour to a clock-stand. A small spherical central area, like aclock in its case, representing the stomach ofthe larva, develops spicules around it, andbecomes the body of the ur
