We wish to present here some ideas on what we do not know about sea urchin gastrulation, and to indicate different approaches being used in our laboratory to address these questions about the cellular and molecular basis of morphogenesis in sea urchin embryos.

As such it is not only an important process, but also one that is complicated and not easily dissected into its component parts. To understand the mechanisms of gastrulation one
