Scientists find gene that makes some snails’ shells coil left; the same species that twist their genitals to mate

Researchers at the University of Nottingham have made groundbreaking discoveries regarding Euhadra snails and their shell coiling. Their study identifies a myosin-encoding gene as crucial in determining the direction of the shell's coiling. Interestingly, both left- and right-coiling snails develop without any embryo-related issues.

This research not only illuminates the unique chirality in snails but also opens doors to understanding variable chirality across the animal kingdom.
