  • Some scyphomedusae were collected from the coasts of Ilgwang, Jeju Harbour, Yeosu, Yokjido Is. and Munyeodo Is. in Korea from May to Nov. 2004. They were indentified into Pelagia noctiluca Forskal, 1775 and Cyanea nozakii Kishinouye, 1891 of the order Semaeostomeae and Nemopilema nomurai Kishinouye, 1922 of the order Rhizostomeae in the class Scyphozoa. They are new to the Korean fauna.

  • Most scyphomedusae jellyfishes recorded in Korean waters are temperate and subtropical species. In the present study, two cold-water jellyfishes from Korean waters are first described. Scyphomedusae were collected from the coasts of Gangneung and Ulsan of the East Sea, and Boryeong, and the eastern area of the Yellow Sea from June 2006 to May 2015. Scyphomedusae collected in Ulsan and Gangneung were identified morphologically as Aurelia limbata Brandt, 1835. Their umbrella was 250-500 mm in width and 30-50 mm in height; the exumbrella was white and the subumbrella was dark brown in color. The vascular system was complex with anastomosed branches. Individuals of this species lived at about 6.6-9.9℃ and 30-50 m depth in Korean waters. Scyphomedusae collected from the center of the Yellow Sea and from Boryeong were identified as Parumbrosa polylobata Kishinouye, 1910. Their umbrella was disc-shaped, 80-200 mm in width and 20-40 mm in height. Its milky white gonads could be seen through the transparent exumbrella. The stomach cavity was round and flat with four interradial cavities connected by subgenital cavities, and the four oral arms were bifurcated and spear-head shaped. Individuals were found at about 6.4-10.0℃ and 40-90 m depth in Korean waters. The identities of both species were confirmed by molecular analysis using nuclear ribosomal DNA sequences.

  • A species of edible Scyphomedusae jellyfish has been used as food by the local people in Ganghwado, Korea since the 1990s. In order to identify this jellyfish, we collected specimens in Ganghwado during September 2013, and compared these specimens with original descriptions made by Kishinouye (1890). Mitochondrial cytochrome oxidase subunit 1 (CO1) sequences of these specimens were compared with those of Rhopilema esculentum retrieved from GenBank. Our specimens were also compared with jellyfish collected in China, previously confirmed as R. esculentum, based on morphological characters and DNA sequences. Using these two methods, the jellyfish specimens caught in Ganghwado were correctly identified as R. esculentum, a species new to Korean waters. This edible jellyfish has been named 'Gisusik-Yonghaepari' as Korean name.

  • 후포의 연안에서 채집된 푸른우산관해파리 (Porpita umbella)와 거제도의 연안에서 채집된 커튼원양해파리(Dactylometra quinquecirrha)가 각각 한국 미기록종으로 판명되어 재기재하여 보고한다. 푸른우산관해파리의 부유기는 연한 갈색의 둥글고 납작한 단추 모양이고 촉수, 개충 그리고 우산의 테두리는 푸른색을 띤다. 커튼원양해파리는 긴 커튼과 같은 신축성 있는 4개의 구엽을 가지고 있다. 관해파리류는 우리나라에서 처음 보고되고 해파리류는 본 연구 결과 3종이 보고된다.

  • The nomenclature of the sea nettle jellyfish from Korea was initially described as Dactylometra quinquecirrha Agassiz, 1862. However its identity has been questioned on the basis of its local distribution and molecular data. Here, we examined morphology and DNA sequences of nuclear rDNA using specimens collected from southern Korean waters in August 2014. Based on morphological characteristics (bell size, umbrella pattern, number of tentacles and lappets) and distribution locality, we reassign the Korean D. quinquecirrha to Chrysaora pacifica (Goette, 1886), and provide a re-description accordingly. The molecular identity of C. pacifica was further confirmed by comparison of nuclear ribosomal DNA sequences.

  • 해파리류의 동물플랑크톤에 대한 포식 파급효과가 식물플랑크톤의 대발생에 어떠 한 영향을 미치는 가를 연구하기 위해, 해파리류, 동물플랑크톤, 식물플랑크톤으로 이 어지는 먹이연쇄내에서 의 상호작용을 미국 뉴욕주에 있는 Reeves만에서 쌍편모 조류 인 Gyrodinium aureolum의 대발생이 있었던 기간을 전후한 1989년 3월 중순에서 7월 초순사이에 조사하였다. 동물플랑크톤의 최대 개체수는 해파리류의 개체수가 감소하기 시작한 4월 중순에서 5월 초사이에 관찰되었으며, 이때 식물플랑크톤의 생물량은 낮게 나타났다. 한편 해파리류의 개체수가 다시 증가하였던 5월 중순부터 동물플랑크톤은 개체수의 감소를 보인 보면, 식물플랑크톤은 대발생을 시작하였다. 이와 같은 결과는 2차 소비자인 해파리류의 포식이 1차 소비자인 돈물플랑크톤의 식물플랑크톤에 미치는 섭식압력의 감소 효과에서 비롯된 것으로 나타났다. 한편, 탄소동위원소를 사용하여 측정한 동물플랑크톤의 섭식률은 대발생 전후에 비해 대발생 중에 현저하게 낮아, 동 물플랑크톤들이 대발생을 일으킨 G. aureolum을 먹이로서 선호하지 않는 것으로 밝혀 졌다.
