| Abstract |
For more than a hundred years the morphology of bivalves was an object of research.
The best way to explore bivalve morphology is on the shell. The shell provides a wide
array of variability and is important for the effective culture of these organisms. In this
study, the right and left valve interiors of the three species belonging to the family
Cyrenidae (Polymesoda bengalensis) and Lucinidae (Codakia tigerina and Anodontia
edentula) were explored for phenotypic variations using Geometric Morphometrics
(GM) tools coupled with Canonical Variance Analysis (CVA), Multivariate Analysis of
Variance (MANOVA), Relative Warp Analysis (RWA), and Kruskal-Wallis test. Ten
(10) anatomical landmark tests were performed, covering the visible morphological
characteristics of the internal shell. The analyses showed that the formation of the hinge
plate, distance of the pallial line, and the orientation of the muscle scar are significantly
different. These features are usually affected by habits and habitats of the particular
species. Hence, these characters are better suited for functional morphological analysis
and should be incorporated when studying intrapopulation and interpopulation
variation |
