Abstract

Three common species of Corbiculidae (Polymesda erosa, P. bengalensis and P. expansa) can be found inhabiting the
mangrove areas in Southeast Asia. The morphometric variations of three species were examined based on 15 morphometric
characters. A total of 16 populations from six localities were analyzed in the present study. Analysis of variance had revealed
significant differences (P<0.05) for LCT/SL and VPM/SL for proportion ratio on morphometric variables among species.
Cluster analysis for these populations formed two groups at 70% of similarity. Morphometric characteristics, such as LCT
and VPM, of Corbiculidae are proposed to differentiate these three species.
