Abstract
Tropical anguillid eels account for two-thirds of all species in the genus Anguilla, however information on the species diversity, biogeography, and life histories is very limited. The anguillid eels found in Southeast Asian waters, i.e. Malaysia, Thailand and Vietnam were identified using molecular genetic analysis after morphological observation. This is the first record of the occurrence of A. marmorata in Thailand and Vietnam that was confirmed by both morphological and molecular genetic analyses. The molecular phylogenetic tree and the haplotype network of A. marmorata in Malaysia, Thailand and Vietnam suggested that the eel might be transported from the western North Pacific spawning area. We also propose possible dispersion and migration of A. marmorata into Southeast Asian waters.
