In 2005, harmful dinoflagellate Cochlodinium polykrikoides was first occurred on July 18 and disappeared on September 12 in the Yeosu waters of the South Sea of Korea. During C. polykrikoides blooms, the species of Protoperidinium was isolated from Jabong Island in Yeosu in the middle of August, 2005. The surface water temperature at the sampling site was , and salinity was 33.1 psu. The specimen was somewhat large in size and was longer than its width. The shape was close to being ovoid, with an apical horn. This study discovered cells with colorless and transparent ingested chain-forming C. polykrikoides. However, this species was not abundant, implying low grazing impact on C. polykkoides.
