Abstract	Con el objetivo de elaborar la lista floristica de diatomeas que son consumidas por abulones adultos, se revisaron contenidos intestinales de especimenes silvestres de abulon azul (Haliotis fulgens) y amarillo (H. corrugata), con la hipotesis de que se encontrarian principalmente formas epifitas, sobre todo de Macrocystis pyrifera. Para ello, se hicieron 7 muestreos entre marzo y septiembre de 2012 en La Bocana, BCS, Mexico. En cada muestreo se recolectaron de 4 a 10 especimenes adultos de H. fulgens y H. corrugata. Los organismos se disecaron para extraer sus contenidos intestinales, los cuales se oxidaron con acido nitrico y alcohol. Las diatomeas montadas con Pleurax se observaron bajo un microscopio con contraste de fases y optica planapocromatica. Asi, se elaboro la primera lista floristica de diatomeas consumidas por abulones adultos que incluyo 151 taxa (especies y variedades) y 2 nuevos registros para la region: Navicula johanrossi y Navicula cluthensis. Entre los 61 generos identificados, los mejor representados fueron: Cocconeis (17 especies), Navicula (15), Amphora (15) y Nitzschia (11); la mayoria fueron formas epifitas, aunque no particularmente de M. pyrifera. La alta riqueza de especies observada confirmo que los adultos de Haliotis spp. no son selectivos al consumir diatomeas.
