Organism at the blastula stage - 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 ]

editor note

TODO - check relationship with epiblast. Note in FMA this is not a subclass of embryo, but in uberon embryo is the whole organism from zygote onwards and thus includes the blastula
