Published in Scientia Marina: http://www.icm.csic.es/scimar/index.php/secId/6/IdNum/14/.The present Atlas is a very useful tool that covers the sagitta otoliths of 348 species, belonging to 99 families and 22 orders of marine teleostean fishes, from the north and central eastern Atlantic and western Mediterranean. It is therefore an extensive guide of morphological and morphometric descriptors. There is a careful description for each species, with excellent sagitta images and numerical descriptors, so that this Atlas goes a step further than previous ones.Peer reviewed
