blastula stage

^ http://purl.obolibrary.org/obo/UBERON_0000108

An early stage of embryonic development in animals. It is produced by cleavage of a fertilized ovum and consists of a spherical layer of around 128 cells surrounding a central fluid-filled cavity called the blastocoel. The blastula follows the morula and precedes the gastrula in the developmental sequence. [ http://en.wikipedia.org/wiki/Blastula ]
