Echinoderms already undergo large-scale metamorphosis during larval development, so there are lots of gene 'switches' that produce different patterning.

The loss of a few of these (say, for "trunk") creates an animal that is a sort of "Oops, All-Arms!" body plan.
A radical evolutionary makeover gave echinoderms their unusual body plan
Gene-expression maps show how starfish evolved their five-fold symmetry.
