Geometric - morphometric study of gastropod shells \kur{Hexaplex trunculus} from Croatian coast line of the Adriatic sea
MACÍK, Jiří
The shape variability of three hundred shells of sea snail Hexaplex trunculus (Linné, 1758) of three sites of Croatian coast line was compared. No criteria were found for distinguishing among males, females and imposex disabled females by traditional morphometry. With the help of traditional morphometry and geometric morphometry, differences in the shape of shells among the three investigated populations were identified. On the shells of H. Trunculus, there were found moderate sexual differences using the geometric-morphometric methods. The results separated females from the remaining two categories (males and masculinized females).
