Jellyfish are important components of the marine ecosystem and present a potential resource for different economic domains (e.g. medicine, food and biotechnology). We present an overview of the current state of jellyfish biodiversity in the Macaronesia region, which includes the archipelagos of the Azores, Madeira, the Canary Islands and Cape Verde, and examine possible biogeography patterns among its archipelagos. Based on a comprehensive literature survey, historical records, richness estimation and biogeographical distribution, our search included organisms belonging to Scyphozoa, Hydrozoa (strictly benthic species excluded) and Ctenophora. Our search detected 229 jellyfish species, with a dominance of holoplankton species, likely reflecting the insular and coastal morphology of the archipelagos. Differences in species richness, endemism and species affinities are found between the Azores, Madeira, Canary and Cape Verde island systems. Shared trend includes the dominance of holoplanktonic hydrozoans, while the second most speciose taxa (Scyphozoa and Ctenophore) vary between the archipelagos. While widespread distributed holoplankton predominate in the area, species with strict affinities suggests a pattern in the spatial distribution of jellyfish, dividing Macaronesia into two biogeographic units: (i) Azores-Madeira-Canary with temperate and subtropical and/or tropical species and (ii) Cape Verde with strictly subtropical and/or tropical species

水母是海洋生态系统的重要组成部分，并为不同经济领域（例如医药，食品和生物技术）提供了潜在资源。我们对马卡罗尼西亚地区（包括亚速尔群岛，马德拉群岛，加那利群岛和佛得角群岛）的水母生物多样性现状进行了概述，并研究了其群岛中可能存在的生物地理格局。基于全面的文献调查，历史记录，丰富度估算和生物地理分布，我们的搜索包括了鳞翅目动物，水生动物（不包括严格的底栖生物）和Ctenophora的生物。我们的搜索发现了229种水母种类，其中以浮游生物种类占优势，这很可能反映了群岛的岛屿和沿海形态。物种丰富度的差异，在亚速尔群岛，马德拉群岛，加那利群岛和佛得角岛系统之间发现有特有性和物种亲和力。共同的趋势包括全浮游水生动物的优势，而第二大特定类群（Scyphozoa和Ctenophore）则在群岛之间有所不同。虽然该地区普遍分布着大量的浮游生物，但亲缘关系严格的物种表明水母的空间分布格局存在，将马卡罗尼西亚划分为两个生物地理单位：（i）亚速尔群岛-马德拉-金丝雀属有温带和亚热带和/或热带物种;和（ii ）佛得角拥有严格的亚热带和/或热带物种 而第二最特殊的分类单元（Scyphozoa和Ctenophore）则在群岛之间有所不同。虽然该地区普遍分布着大量的浮游生物，但亲缘关系严格的物种表明水母的空间分布格局存在，将马卡罗尼西亚划分为两个生物地理单位：（i）亚速尔群岛-马德拉-金丝雀属有温带和亚热带和/或热带物种;和（ii ）佛得角拥有严格的亚热带和/或热带物种 而第二最特殊的分类单元（Scyphozoa和Ctenophore）则在群岛之间有所不同。虽然该地区普遍分布着大量的浮游生物，但亲缘关系严格的物种表明水母的空间分布格局存在，将马卡罗尼西亚划分为两个生物地理单位：（i）亚速尔群岛-马德拉-金丝雀属有温带和亚热带和/或热带物种;和（ii ）佛得角拥有严格的亚热带和/或热带物种
