Abstract[EN] The sagittal otolith of 348 species, belonging to 99 families and 22 orders of marine Teleostean fishes from the north and central eastern Atlantic and western Mediterranean were described using morphological and morphometric characters. The morphological descriptions were based on the otolith shape, outline and sulcus acusticus features. The morphometric parameters determined were otolith length (OL, mm), height (OH, mm), perimeter (P; mm) and area (A; mm2) and were expressed in terms of shape indices as circularity (P2/A), rectangularity (A/(OL×OH)), aspect ratio (OH/OL; %) and OL/fish size. The present Atlas provides information that complements the characterization of some ichthyologic taxa. In addition, it constitutes an important instrument for species identification using sagittal otoliths collected in fossiliferous layers, in archaeological sites or in feeding remains of bony fish predators
[ES] Se han descrito morfológica y morfométricamente los otolitos sagitta de 348 especies, pertenecientes a 99 familias y 22 ordenes, procedentes de Atlántico Oriental Central y Norte y el Mediterráneo occidental. La descripción morfológica se ha basado en las caraterísticas de la forma del otolito, de su contorno y del surco acústico. Se han dterminado los parámetros biométricos siguientes: longitud del otolito (OL, mm), anchura (OH, mm), perímetro (P; mm) y área (A; mm2) y se han expresado con distintos índices de forma: circularidad (P2/A), rectangularidad (A/(OL×OH)), aspecto (OH/OL; %) y OL/longitud del pez. Este atlas da nueva información para complementar la caracterización de algunos taxones ictiológicos. Además, constituye un instrumento importante para identificar especies mediante otolitos sagitta en yacimientos fósiles y arqueológicos o en estudios de alimentación de especies ictiófagas
