description Introduction: The order Euryalida is represented by fragile ophiuroids with long and slender arms that can be ramified. Species within the family Gorgonocephalidae are characterized by the presence of tiny hooklets on the dorsal aspect of their arms. There are very few published studies referring to species of the family Gorgonocephalidae inhabiting Mexican waters. Objective: To review the taxonomic status of the species belonging to this taxonomic family, identifying their diagnostic taxonomic characteristics to create an illustrated guide of species kept at the CNE, UNAM. Methods: Specialized bibliography of the Gorgonocephalidae family was gathered. Subsequently, all the specimens from the CNE were photographed using Scanning Electron and Multifocal Microscopy photography, to show the structures of taxonomic relevance. Results: A total of 193 specimens corresponding to eight genera and nine species were reviewed. The genus Astrocaneum presented the highest species richness. Conclusions: For the species identified in this study and for the sake of accurate identification, morphological characters such as the shape of hooklets and arm plates were highlighted. Introducción: El orden Euryalida está formado por ofiuros frágiles con brazos delgados, largos y a veces ramificados. Las especies de la familia Gorgonocephalidae se caracterizan por la presencia de diminutos ganchos en el lado dorsal de sus brazos. Los estudios que refieren especies de la familia Gorgonocephalidae que habitan en aguas mexicanas son escasos. Objetivo: Realizar la revisión taxonómica de dicha familia, reconociendo los caracteres taxonómicos diagnósticos para generar una guía ilustrada de cada una de las especies que se encuentran en la CNE del ICML, UNAM. Métodos: Se recopiló toda la bibliografía especializada de la familia, posteriormente con ayuda de fotografías de MEB y multifocal se fotografiaron los especímenes de la CNE para destacar las estructuras de importancia taxonómica. Resultados: se revisaron un total de 193 ejemplares ...

Species within the family Gorgonocephalidae are characterized by the presence of tiny hooklets on the dorsal aspect of their arms. There are very few published studies referring to species of the family Gorgonocephalidae inhabiting Mexican waters. Objective: To review the taxonomic status of the species belonging to this taxonomic family, identifying their diagnostic taxonomic characteristics to create an illustrated guide of species kept at the CNE, UNAM. Methods: Specialized bibliography of the Gorgonocephalidae family was gathered. Subsequently, all the specimens from the CNE were photographed using Scanning Electron and Multifocal Microscopy photography, to show the structures of taxonomic relevance. Results: A total of 193 specimens corresponding to eight genera and nine species were reviewed. The genus Astrocaneum presented the highest species richness. Conclusions: For the species identified in this study and for the sake of accurate identification, morphological characters such as the shape of hooklets and arm plates were highlighted. Introducción: El orden Euryalida está formado por ofiuros frágiles con brazos delgados, largos y a veces ramificados. Las especies de la familia Gorgonocephalidae se caracterizan por la presencia de diminutos ganchos en el lado dorsal de sus brazos. Los estudios que refieren especies de la familia Gorgonocephalidae que habitan en aguas mexicanas son escasos. Objetivo: Realizar la revisión taxonómica de dicha familia, reconociendo los caracteres taxonómicos diagnósticos para generar una guía ilustrada de cada una de las especies que se encuentran en la CNE del ICML, UNAM. Métodos: Se recopiló toda la bibliografía especializada de la familia, posteriormente con ayuda de fotografías de MEB y multifocal se fotografiaron los especímenes de la CNE para destacar las estructuras de importancia taxonómica. Resultados: se revisaron un total de 193 ejemplares ...
