Research Abstract

Morphology of gonophores (gonads) of Hydrozoa is exceptionally diverse unlike other Cnidaria. Our phylogenetic study revealed that this diversity of gonophore morphology was reflected by differences among taxon in the origin and growth process of gametes. Furthermore, it was considered that these differences in gametogenesis were caused by the shift in position of gonads from the gastric side to body surface by the reduction of body size in Hydrozoa.
