Name: late swimming blastula stage

ECAO ID: 0000310

Definition: "The embryo has started elongated along the animal-vegetal axis. Its vegetal region has further continued to thicken and it is marked by a characteristic 'V' shape formed by the blastocoel at the level of the cells constituting the vegetal plate, thereby pointing to the vegetal pole. At the animal pole, the embryo is characterized by the presence of an apical tuft."
