Abstract

In 2022, during a survey of intertidal fauna around Jindo located in the Dadohaehaesang National Park in the South Sea, epizoic hydroids attaching onto seagrass (Zostera sp.) growing on soft sediments were collected. Through taxonomic examination, an unrecorded species, Ectopleura radiata, is newly added to the hydrozoan fauna of Korea. In addition, DNA barcoding for species from Ectopleura and Tubularia clarified the distinction among morphologically indistinguishable species without gonophores. Up to now, only one species, E. crocea, has been reported in Korea. Through this study, a total of two species belonging to genus Ectopleura have been reported in Korean waters so far.
