Abstract:
In this study, the distribution of Nemopilema nomurai in the waters of Mijo-myeon, Namhae and Gijang-gun, Busan was analyzed; furthermore, echo counting and echo integration methods were used to compare the distribution density. The acoustic system used in the study was a split beam scientific echosounder operating at 38 and 120 kHz (EK-60, Simrad, Norway). Echo counting and echo integration methods were used to determine the density of N. nomurai distributed in the survey areas. The distribution of N. nomurai by water columns, estimated using an echo counting method, was concentrated at approximately 10 m deep in the waters of Mijo, Namhae and 10–50 m deep in the waters of Gijang, Busan; moreover, the distributed depth varied by the surveyed date and time. It was shown that analyzing the acoustic scattering strength of jellyfish obtained from the echo counting method would be more effective for distributional survey of N. nomurai with two frequency system.

Abstract:
Cephennomicrus Reitter, 1907 (Staphylinidae, Scydmaeninae, Cephenniini) of Japan and Taiwan is revised. Four species groups are established for the following species: the nomurai group—C. nomurai (Jałoszyński & Hoshina, 2003) (Japan), C. hobbiti (Jałoszyński & Hoshina, 2003) (Japan), C. disjunctus (Jałoszyński, S. Arai & K. Arai, 2004) status n. (Japan), C. inflatus sp. n. (Taiwan), and C. crucifer sp. n. (Taiwan); the taiwanensis group—C. taiwanensis (Jałoszyński, 2004) (Taiwan), C. iriomotensis sp. n. (Japan), C. nagoanus sp. n. (Japan), C. tsurui sp. n. (Taiwan), C. delicatissimus sp. n. (Taiwan), and C. imago sp. n. (Taiwan); the japonigenus group—C. japonigenus (Jałoszyński & Hoshina, 2003) (Japan), and C. pseudojaponigenus sp. n. (Japan); the fujianus group—C. fujianus (Jałoszyński, 2005) (from China, not treated in this paper), and C. pseudofujianus sp. n. (Taiwan). Three species remain incertae sedis within the genus: C. okinawanus (Jałoszyński, S. Arai & K. Arai, 2004) (Japan), C. cactiformis (Jałoszyński & Hoshina, 2003) (Japan), and C. taitungensis sp. n. (Taiwan). Habitus of all treated species and aedeagi are illustrated. Detailed morphology of the nomurai and taiwanensis species groups was studied, described and illustrated based on disarticulated specimens of C. nomurai and C. delicatissimus. Comparative study suggests a separate position of the nomurai group as a subgenus or genus; however, Oriental Cephennomicrus must be studied in detail before formal taxonomic changes can be made.

Abstract:
Two new species of the family Leptochitonidae, Leptochiton pumilus sp. nov. and Terenochiton nomurai sp. nov. are described from the tropical and subtropical shallow waters of the West Pacific. L. pumilus from the Philippines and Papua New Guinea has a net-like sculpture on the shell which is rather rare feature in the genus. In this genus, so far only three species have hitherto been known in the tropical shallow waters, in contrast to more than 130 other extant species which are living in the deep cold waters and high latitudes. T. nomurai from Ryukyu Islands is the second representative of the genus Terenochiton Iredale, 1914 which was recently reinstated for Leptochiton norfolcensis (Hedley et Hull, 1912), and is characterized by having rudiments of the insertion plates in all valves. T. nomurai closely resembles the type species, but differs in the arrangement of the aesthete pores on the granules of the tegmentum, and less developed rudiments of the insertion plates. Key words: chitons, Leptochiton, Terenochiton, new species, the Philippines, Japan, Papua New Guinea. Описаны два новых вида семейства Leptochitonidae, Leptochiton pumilus sp. nov. и Terenochiton nomurai sp. nov. из тропических и субтропических мелководий западной Пацифики. L. pumilus c Филиппин и Папуа – Новой Гвинеи имеет сетчатовидную скульптуру на раковине, что является довольно редким признаком в этом роде. В этом роде только три вида известны до настоящего времени в тропических мелководьях, в противоположность более чем 130 другим современным видам, которые живут в глубоких холодных водах и в высоких широтах. T. nomurai из островов Рюкю является вторым представителем рода Terenochiton Iredale, 1914, который был недавно восстановлен для Leptochiton norfolcensis (Hedley et Hull, 1912) и характеризуется наличием рудиментов инсерционных пластинок на всех щитках. T. nomurai сходен с типовым видом рода, но отличается расположением пор эстетов на зернах тегментума и менее развитыми рудиментами инсерционных пластинок. Ключевые слова: хитоны, Leptochiton, Terenochiton, новые виды, Филиппины, Япония, Папуа Новая Гвинея.

Abstract Hirose, M., Mukai, T., Hwang, D., and Iida, K. 2009. The acoustic characteristics of three jellyfish species: Nemopilema nomurai, Cyanea nozakii, and Aurelia aurita. – ICES Journal of Marine Science, 66: 1233–1237. Reports about jellyfish damaging nets and reducing fish catches are increasing, and data on the abundance and distribution of various jellyfish species are needed to forecast where and when their blooms will happen. Acoustic techniques can be used to obtain this information if the acoustic characteristics of the targets are known. This is a study of acoustic scattering from three jellyfish species: Nemopilema nomurai (order Rhizostomeae), Cyanea nozakii (Semaeostomeae), and Aurelia aurita (Semaeostomeae). Target strength (TS) at 38, 120, and 200 kHz, specific density, and sound speed were measured with live specimens. Specific densities were measured using the displacement–volume–weight and the dual-density methods. The sound speeds were estimated using the time-of-flight method. The reduced TS (RTS), i.e. the TS normalized by bell area, was smaller for N. nomurai (bell diameter range 19–38 cm) than for C. nozakii (bell diameter range 30–40 cm), and the differences in RTS between the species were 17.8, 12.6, and 5.8 dB at 38, 120, and 200 kHz, respectively. The respective sound-speed contrast h and density contrast g were 1.0008 ± 0.009 (mean ± s.d.) and 1.004 ± 0.015 for N. nomurai; 1.038 and 1.073 for one C. nozakii; and 1.0001 ± 0.025 and 0.989 ± 0.019 for A. aurita.

Abstract:
The East Asian marginal seas are among the most productive fisheries grounds. However, in recent decades they experienced massive proliferations of jellyfish that pose vast challenges for the management of harvested fish stocks. In the Korean Peninsula, the common bloom-formers Scyphozoan species Aurelia coerulea and Nemopilema nomurai are of major concern due to their detrimental effects on coastal socio-ecological systems. Here, we used pluriannual field observations spanning over 14 years to test the extent of climate influence on the interannual variability and bloom dynamics of A. coerulea and N. nomurai. To depict climate-jellyfish interactions we assessed partitioning effects, direct/indirect links, and the relative importance of hydroclimate forces on the variability of these species. We show that jellyfish interannual patterns and bloom dynamics are shaped by forces playing out at disparate scales. While abundance changes and earlier blooms of A. coerulea were driven by local environmental conditions, N. nomurai interannual patterns and bloom dynamics were linked with regional climate processes. Our results provide a synoptic picture of cascading effects from large scale climate to jellyfish dynamics in the Korean Peninsula that may affect fisheries sustainability due to the prominent detrimental impact these species have in the region.

Abstract:
Jellyfish envenomations result in extensive dermatological symptoms, clinically named as jellyfish dermatitis, which can seriously affect the daily activities and physical health of people. Inflammatory response accompanies the whole process of jellyfish dermatitis and the complexity of jellyfish venom components makes it difficult to treat jellyfish dermatitis symptoms effectively. Moreover, inhibiting inflammation is essential for the treatment of jellyfish stings and exploring the main components of jellyfish venom that cause inflammation is an urgent research area. In this study, the inhibitory effects of matrix metalloproteinase (MMP) inhibitors for venom-induced inflammation were explored at a cellular level. The expression of the three inflammatory factors, IL-6, TNF-α and MCP-1 in two skin cell lines, human keratinocyte cells (HaCaT) and human embryonic skin fibroblasts cells (CCC-ESF-1), at the cellular level, after treatment with the inhibitors of jellyfish Nemopilema nomurai (N. nomurai) nematocyst venom (NnNV-I), were determined. The results showed that inhibitors of MMP can significantly reduce the toxic effects of jellyfish Nemopilema nomurai nematocyst venom (NnNV) to skin cells. The expression levels of the three inflammatory factors IL-6, MCP-1, and TNF-α in the cells were also significantly decreased, indicating that MMPs in jellyfish venom are probably vital factors leading to jellyfish dermatitis. This study is beneficial in the prevention and treatment of jellyfish stings.

Abstract:
Jellyfish are rich in resources and widely distributed along coastal areas. As a potential approach to respond to jellyfish blooms, the use of jellyfish-derived products is increasing. The citrus spider mite (Panonychus citri) is one of the key citrus pests, negatively impacting the quality and quantity of oranges. Due to the resistance and residue of chemical acaricides, it is important to seek natural substitutes that are environmentally friendly. The field efficacy of the venom from the jellyfish Nemopilema nomurai against P. citri was assayed in a citrus garden. The frozen N. nomurai tentacles were sonicated in different buffers to isolate the venom. The venom isolated by PBS buffer (10 mM, pH 6.0) had the strongest acaricidal activity of the four samples, and the corrected field efficacy 7 days after treatment was up to 95.21%. This study demonstrated that jellyfish has potential use in agriculture.

Abstract:
Nowadays, proliferation of jellyfish has become a severe matter in many coastal areas around the world. Jellyfish Nemopilema nomurai is one of the most perilous organisms and leads to significant deleterious outcomes such as harm to the fishery, damage the coastal equipment, and moreover, its envenomation can be hazardous to the victims. Till now, the components of Nemopilema nomurai venom (NnV) are unknown owing to scant transcriptomics and genomic data. In the current research, we have explored a proteomic approach to identify NnV components and their interrelation with pathological effects caused by the jellyfish sting. Altogether, 150 proteins were identified, comprising toxins and other distinct proteins that are substantial in nematocyst genesis and nematocyte growth by employing two-dimensional gel electrophoresis and matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI/TOF/MS). The identified toxins are phospholipase A2, phospholipase D Li Sic Tox beta IDI, a serine protease, putative Kunitz-type serine protease inhibitor, disintegrin and metalloproteinase, hemolysin, leukotoxin, three finger toxin MALT0044C, allergens, venom prothrombin activator trocarin D, tripeptide Gsp 9.1, and along with other toxin proteins. These toxins are relatively well characterized in the venoms of other poisonous species to induce pathogenesis, hemolysis, inflammation, proteolysis, blood coagulation, cytolysis, hemorrhagic activity, and type 1 hypersensitivity, suggesting that these toxins in NnV can also cause similar deleterious consequences. Our proteomic works indicate that NnV protein profile represents valuable source which leads to better understanding the clinical features of the jellyfish stings. As one of the largest jellyfish in the world, Nemopilema nomurai sting is considered to be harmful to humans due to its potent toxicity. The identification and functional characterization of its venom components have been poorly described and are beyond our knowledge. Here is the first report demonstrating the methodical overview of NnV proteomics research, providing significant information to understand the mechanism of NnV envenomation. Our proteomics findings can provide a platform for novel protein discovery and development of practical ways to deal with jellyfish stings on human beings.
