Species composition, diversity and biomass of jellyfish (Cnidaria and Ctenophora), with their spatiotemporal distributions, were analyzed in the upper 1500 m of the Oyashio front, the Transition zone and the Kuroshio extension, off Tohoku, northeastern Japan, between May 2005 and March 2006. Species composition and abundance differed remarkably between the shallower layer and the deeper layer at the boundary of 300-500 m depth, where water density was within the range of the North Pacific Intermediate Water. In the deeper layer, diversity reached its peak with the appearance of 27 taxa common in all the regions throughout the year, though abundance was low. Pantachogon haeckeli and Crossota rufobrunnea were dominant in the deeper layer. The possibility of diel vertical migration was suggested in two midwater species: Euphysa japonica and Atolla vanhoeffeni. In the Oyashio waters, jellyfish abundance was much higher than in the Transition waters and Kuroshio-derived waters, but with low diversity, dominated by large numbers of Aglantha digitale and Dimophyes arctica. High values of diversity were found in the Kuroshio-derived waters with various tropical and warm-water species, especially calycophoran siphonophores being present. In the Transition waters, diversity was relatively high, with co-occurrence of warm-water species and cold-water species. Jellyfish biomass tended to be high in the midwater zone due to the occurrence of large species, particularly Scyphozoa. Carbon-based jellyfish biomass calibrated with other studies exceeded that of other organism groups.

“…In situ observations on the gelatinous zooplankton community of the midwater zone that include these fragile components are very few and far between, with the notable exception of work done off California (Haddock and Case 1999) and around Japan (e.g. Hunt and Lindsay 1999;Vinogradov and Shushkina 2002;Toyokawa et al 2003;Lindsay 2005;Lindsay and Hunt 2005;Lindsay and Miyake 2007), and scattered reports from the northern Atlantic (Youngbluth et al 2008), the south-west Indian Ocean (Lindsay et al 2000) and the Arctic Ocean . Most of these reports are from areas without active venting.…”

A series of dives around the Hatoma Knoll, Okinawa Trough, have revealed a diverse community of gelatinous midwater animals. Many of these animals are potential predators of the larvae of hydrothermal vent-associated organisms. Due to the lack of published information on the midwater fauna of the Okinawa Trough, this paper endeavours to present a synopsis of the macroplanktonic gelatinous faunal elements present in and around the vent site at all depths where vent larvae may occur-from the surface to the benthopelagic layer. Three pelagic tunicates, eight ctenophores, seven siphonophores, eight hydrozoan medusae and two syphozoan medusae were recognized. Taxonomic treatments and comments on distribution and ecology are provided where such information exists. Keywords

“…were concentrated at depth and tended to be most abundant near the 25.0 isopycnal and in areas of lowest particle abundance. These ctenophores are known to have high clearance rates, and could potentially feed on marine snow aggregates exported from above the thermocline, as well as large copepods, euphausiids, and lobate ctenophores that venture to deeper waters (Haddock, 2007;Reeve et al, 1978;Toyokawa et al, 2003). Since some lobate ctenophores have been demonstrated to alter their swimming speed and vertical distribution in the presence of Beroe spp.…”
