  abstract = {{I}ncreasing speed and magnitude of global change threaten the world's biodiversity and particularly coral reef fishes. {A} better understanding of large-scale patterns and processes on coral reefs is essential to prevent fish biodiversity decline but it requires new monitoring approaches. {H}ere, we use environmental {DNA} metabarcoding to reconstruct well-known patterns of fish biodiversity on coral reefs and uncover hidden patterns on these highly diverse and threatened ecosystems. {W}e analysed 226 environmental {DNA} (e{DNA}) seawater samples from 100 stations in five tropical regions ({C}aribbean, {C}entral and {S}outhwest {P}acific, {C}oral {T}riangle and {W}estern {I}ndian {O}cean) and compared those to 2047 underwater visual censuses from the {R}eef {L}ife {S}urvey in 1224 stations. {E}nvironmental {DNA} reveals a higher (16%) fish biodiversity, with 2650 taxa, and 25% more families than underwater visual surveys. {B}y identifying more pelagic, reef-associated and crypto-benthic species, e{DNA} offers a fresh view on assembly rules across spatial scales. {N}evertheless, the reef life survey identified more species than e{DNA} in 47 shared families, which can be due to incomplete sequence assignment, possibly combined with incomplete detection in the environment, for some species. {C}ombining e{DNA} metabarcoding and extensive visual census offers novel insights on the spatial organization of the richest marine ecosystems.},
