    Description: Se presenta información descriptiva y ecológica de nueve especies del género Coryphopterus (Pisces: Gobiidae) colectadas en los arrecifes, principalmente coralinos, del Caribe colombiano (incluyendo la Isla de Providencia). Se incluye además una-clave para identificar las especies. La más común en los muéstreos fue C. personatus (67%), seguida por C. eidolon (52%), C. dicrus (21%), C. glaucofraenum (27%); C. thrix (19%), C. tortugae (10%), C. lipernes (9%), C. hyalinus (4%) y C. alloides (3%). Se observaron diferencias regionales importantes en relación con su presencia y abundancia. Las poblaciones del Caribe continental colombiano tienden a ser más pigmentadas que las de regiones norteñas del Atlántico oeste trópica!, probablemente a causa de la presencia de sedimentos oscuros terrígenos en los fondos arrecifales del sur del Caribe. Los datos preliminares sobre la alimentación de ocho especies sugieren que el género es omnívoro y consume cantidades importantes de detritus, además de variados microinvertebrados. Algunas especies ingieren también algas.
    Description: Descriptive and ecological information on nine species of the gobüd fish genus Coryphopterus, collected mainly in coral reefs of the Colornbian Caríbbean (including Isla de Providencia), ¡s preseníed; a key for species identification is also included. The most common species in the samples was C. personatus (67%), followed by C. eidolon (52%), C. dicrus (27%), C. glaucofraenum (27%), C. thrix (19%), C. tortugae (10%), C. lipernes (9%), C. hyaiinus (4%) and C. alloides (3%); importan! differences in their regional ocurrence and abundance were detectad. Colornbian continental Caríbbean populations tend to be more pigmented than those of northern regions of the tropical western Atlantic, probably because southern Caríbbean reefs have terrígenous dark sedírnents. Preliminary data about the feeding habits of eight species suggest that the genus is omnivorous, eating important amounts of detritus and a variety of microínvertebrates; some species also íngest algae.
