Abstract
The anguillid eels found in Peninsular Malaysia were identified using a morphological analysis and that identification was
further validated as Anguilla bengalensis bengalensis and Anguilla bicolor bicolor by an analysis of the eels’ mitochondrial
cytochrome oxidase subunit I (COI) sequences. Because of the difficulty of accurately identifying tropical eels solely on morphological
analyses, previous studies had reported the occurrence of the tropical eel species Anguilla marmorata in Peninsular
Malaysia. This study suggests the occurrence of Anguilla bengalensis bengalensis in Malaysian waters, confirmed by both
morphological and molecular genetic analyses. Anguilla bicolor is further confirmed as the subspecies of Anguilla bicolor
bicolor by molecular genetic analyses. The present study also suggests that accurate tropical eel species identification requires
validation by molecular genetic analysis after a morphological observation.
