Ctenochaetus marginatus (Valenciennes) (Pisces: Acanthuridae) in the Gorgona Island: First record of the genus in the Colombian PacificAbstract
The genus Ctenochaetus is reportad in the waters of the Colombian Pacific based on two specimens of C. marginatus (Valenciennes) collected in 1993 at Gorgona Island (2°59' N, 78° 12' W). These specimens differ inseveral morphometric characteristics from thosepreviously examined. Such differences appear to be an artifact of the small number of specimens formerly examined and the consequent narrow ranges reportad. We suggest that temperature variability affects the distribution of C. marginatus in the tropical eastern Pacific.El género es Ctenochaetus reportad en las aguas del Pacífico colombiano a partir de dos especímenes de C. marginatus (Valenciennes) recogidos en 1993 en la Isla Gorgona (2 ° 59 'N, 78 ° 12' W). Estos ejemplares difieren inseveral características morfométricas de thosepreviously examinados. Estas diferencias parecen ser un artefacto del pequeño número de muestras examinadas anteriormente y reportad los rangos estrechos consecuente. Sugerimos que la variabilidad de la temperatura afecta la distribución de marginatus C en el Pacífico tropical oriental.
