Blastula. The cells of the morula form a hollow sphere, the blastula. The cavity of the blastula is the blastocoel. The blastula possesses an animal and a vegetal pole. The animal pole of the sea urchin blastula is characterized by a tuft of cilia.

This is known as the blastula (blas'ch3-l3), and the cavity inside as the blastocoel (blas't3-sel', Figure 8-2). The changes in the form of the beginning embryo have so far been due to cell division only and not to any movement of the cells.
