PLUTEUS TO URCHIN

The pluteus larva grows over the period of 4-6 weeks, till it is big enough and developed enough to metamorphose. Metamorphosis itself takes place in only a few hours time. The "skeleton" of the pluteus becomes the spines of the new sea urchin. The gut transforms into the test [shell] of the sea urchin.
