    Our analysis of mitochondrial (COI, 16S) and nuclear (ITS1 and ITS2) gene fragments resulted in the discovery of unique polymorphism in the life cycle of Sarsia lovenii from the White Sea. This polymorphic species exhibits two types of gonophores: hydroids produce both free-swimming medusae and attached medusoids (phenotypic polymorphism).
    ( b) Sarsia lovenii; the gonophore type of each haplotype is colour coded. The relative size of circles is proportional to the number of sequences of that same haplotype. The haplotype network of S. lovenii was represented by five haplotypes, mostly including specimens from the White Sea.
    In our manuscript we study the life cycle of corynid hydrozoan Sarsia lovenii 22, which possibly represent a potential model system for examining the mechanism of the gain or loss of life-history stages in hydrozoans. The hydroid S. lovenii was often been confounded with Sarsia tubulosa 23 going back to investigations of XIX century 24, 25, 26, 27.
    Our results suggest the existence of two gonophore types within the species Sarsia lovenii. Medusa-like gonophores without tentacles and ocelli (eumedusoids) are a common type of gonophore that is well known in S. lovenii, w hile we demonstrated for the first time that hydroids produce free-swimming medusae as well.
