  abstract = {{A}im: {I}dentify biogeographic boundaries that delineate the distribution of species assemblages along global non-insular coastlines, characterise the potential barriers responsible for biogeographic boundaries and realign coastal biogeographic provinces. {L}ocation: {G}lobal. {T}ime {P}eriod: {N}ot applied. {M}ajor {T}axa {S}tudied: {A}nimalia. {M}ethods: {G}lobal databases of marine animals were used to define biogeographic boundaries as regions that concentrate species range limits. {T}o mitigate sampling bias inherent in uneven presence records in biodiversity databases, we applied a resampling methodology. {W}e used the identified dispersal barriers to divide the study area into ecoregions in order to realign coastal biogeographic provinces. {T}hese ecoregions were then clustered into biogeographic provinces based on the similarity of their biodiversity. {R}esults: {W}e identified 24 biogeographic boundaries along the coastlines of the {A}mericas and 27 along {A}fro-{E}urasia. {T}he 52 ecoregions delimited by the biogeographic boundaries were classified into 23 biogeographic provinces. {I}n most cases, the proportion of exclusive species within each province was higher than 25%. {W}hen comparing the proportion of exclusive species to the previous classifications of biogeographic provinces, a higher proportion was found. {O}f the 21 boundaries of the new biogeographic provinces, nine are aligned with and six are close to previous boundaries between the biogeographic provinces or realms defined in previous studies. {O}ur analysis revealed the presence of 6 additional subdivisions and significant realignments within the marine biogeographic provinces. {M}ain {C}onclusions: {T}he objective data-driven approach was effective to identify biogeographic boundaries and realign biogeographic provinces. {M}ost boundaries were associated with strong thermohaline gradients, which typically occur along water-mass fronts due to converging currents, upwelling or river discharge. {S}uch processes, in conjunction with geomorphology and circulation patterns, interact to restrict the dispersal of marine organisms by restricting movement and filtering species according to their ecological niches.},
