One of the most notable variations observed in the morphology of the invasive giant African land snail Achatinafulica is the different banding patterns and shell shape morphology. This study aims to assess the correlation of shell shape and banding patterns among populations of A. fulica. Samples were collected from 15 different provinces in the Philippines. A total of 14 banding patterns were assigned based on the streaks observed on the body whorl. Generally, relative warp analysis showed variation in shell shape which could be slender shaped or round-looking shells. A varied spire-whorl length and aperture shape was also observed in the samples. Histograms and box-and-whiskers plots illustrated multimodal variationson the shell shapes of the banding patterns. Canonical variance analysis scatter plots presentedoverlapping of populations of the different banding patterns. Although there were no observable differences on the mean shapes of the different banding patterns, the MANOVA/CVA scores, Kruskal-Wallist test, and Cluster analysis showed significant morphology variations. The scatters distribution and short distance of variation suggest a wide intrapopulation variation. The findings of this study noted that although there were differences and similarities in the shell shapes or mean shapes of a banding pattern, it is not substantial to conclude that genetics or environmental factor alone caused the phenomena.
