Through a taxonomic study on solitary corals collected from subtidal zones of South and East Seas from 2019 to 2022, Paracyathus rotundatus, an unrecorded species belonging to family Caryophylliidae, is newly added to the anthozoan fauna of Korea. In addition, comparing partial 16S rRNA sequences with a length of 269 bp according to color variation clarified that there were no sequence differences among specimens with color variation, indicating that the color variation is due to intraspecific variation. As a result of this study, a total of 7 genera and 8 species belonging to the Caryophylliidae family have been reported in Korean waters so far.

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.
