Definition:The thickend rim of the blastoderm evident during late blastula and gastrula stages[FishBase]. Embryonic structure which is a uniform thickened annulus at the blastoderm margin, consisting of two layers in addition to the EVL, the epiblast and the hypoblast. The germ ring is formed by the involution of the blastoderm back upon itself[ZFA].
