AbstractThe present study aimed to identify, for the first time, the global hotspots of coastal cephalopod richness, namely cuttlefishes (families Sepiidae, Sepiolidae, Sepiadariidae and Idiosepiidae), squids (family Loliginidae) and octopuses (family Octopodidae), and to assess their latitudinal gradient of species richness (LGRS). A presence/absence database was created according to Marine Ecoregions of the World, which revealed that the most diverse ocean was the Pacific(with 212 species), followed by the Indian (151 species) and Atlantic (103 species) Oceans. Within the 232 ecoregions considered, the highest cephalopod richness value was reached in the Central Kuroshio Current ecoregion, with 64 species, followed by theEast China Sea (59 species) and the Eastern Philippines (48 species). Nonetheless, the location of the hotspots varied greatly among the different taxonomic groups. Regarding the association between latitude and species richness, the peak of cephalopod richness varied among oceans, and only the squids showed a unimodal distribution with latitude. In contrast, cuttlefish, octopods and all cephalopods together revealed bimodal distributions, always with the major peak of species richness in the northern hemisphere. These findings highlight the notion that the shape and symmetry of LGRS are not universal –i.e. there are no single causal predictors to explain the latitudinal zenith locations within the same taxa
