Leatherback Dermochelys coriacea (Vandelli, 1761) sea turtles, are known to roam across entire oceans in search of high densities of their jellyfish food. Although this predator-prey relationship is well established, considerations of leatherback foraging behaviours are often hampered by a lack of information on the prey available to them in different regions. Therefore, to provide an overview for future studies we synthesise our current knowledge of jellyfish distributions and seasonality throughout the Northeast Atlantic and highlight known hotspots for the turtles themselves.KEY WORDS: Dermochelys, gelatinous zooplankton, medusae, Rhizostoma, La Rochelle, Pelagia and salps. RESUMENLas tortugas laúd Dermochelys coriacea (Vandelli, 1761), se conocen por recorrer océanos enteros, en busca de aprovisionamiento o alimento en zonas con grandes cantidades de zooplancton gelatinoso. Aunque la relación depredador-presa es bien conocida, el comportamiento de esta especie en relación a su alimentación es incompleta, debido a la falta de datos existentes en relación a la disponibilidad que existe de sus presas en las distintas regiones. Para proporcionar una visión general de la información relevante en este ámbito, hemos resumido el conocimiento que se tiene del zooplancton gelatinoso, su distribución y estacionalidad a lo largo del Noreste Atlántico y hemos querido resaltar puntos o zonas de especial importancia para las tortugas. PALABRAS CLAVES:Dermochelys, zooplancton gelatinoso, medusae, Rhizostoma, La Rochelle, Pelagia y salpas. LABURPENALarruzko dortokak Dermochelys coriacea (Vandelli, 1761), ozeanoetan barrena elikatzeko plankton lirdingatsuan aberats diren guneen bila ibiltzeagatik dira ezagunak. Naiz eta harrapakari-harrapakin harremana aski ezaguna izan, bere elikatzeko portaerak utsune handiak ditu oraindik, bere harrapakinen inguruko informazio ezagatik. Gai honekiko ikuspegi zabal bat ematearren, gaur egun zooplankton lirdingatsuaren inguruan dugun informazio esanguratsua laburbildu dugu artikulu honetan, Atlantiko Iparekialdean duen distribuzio eta urtaroaren arabeherako aldaketak eta bereziki itsas dortokentzat garrantzitsuak diren guneak azpimarratu nahi izan ditugu. KITAMURA, 2004). Some jellyfish (siphonophores) have been described as some of the longest animals on the planet measuring 20 metres long , in Bone 1998. This diversity of species is found in all oceans, from surface waters to the aphotic depths, with some eking out an unusual existence lying on the seafloor. GAKO-HITZAKThe manner in which jellyfish aggregate also varies markedly between species. Many form spectacular aggregations with many millions of individuals closely grouped, whereas other species are widely dispersed at much lower densities (GRAHAM et al., 2001). Taking this to the extreme, some animals which appear as individuals are in fact colonies such as the Portuguese Man-o-War Physalia physalis (Linnaeus, 1758) and Pyrosoma atlanticum (Péron, 1804) whilst other species can occur in both singular and colonial forms (e.g...
