-
Any of many marine echinoderms, of the class Echinoidea, commonly found in shallow water, having a complex chewing structure named Aristotle's lantern.
Approximately 20% of sea urchins are direct-developers, meaning that they bypass the pluteal larval stage and develop directly into an adult sea urchin.

Leahy, Chapter 1: Laboratory Culture of Strongylocentrotus purpuratus Adults, Embryos, and Larvae, Thomas E. Schroeder (editor), Methods in Cell Biology, Volume 27: Echinoderm Gametes and Embryos, page 2, Of the many species of sea urchins utilized in biological research today the most widely used in North America is probably the purple sea urchin, Strongylocentrotus purpuratus.
