Tramite una manipolazione meccanica allo stato embrionale, all'università di Tokyo gli scienziati sono riusciti ad invertire il verso di crescita della spirale del guscio di alcuni esemplari di Lymnaea stagnalis (Linné, 1758). Di norma sono i geni a determinare lo sviluppo ontogenetico dei molluschi. Il senso della spirale della conchiglia e la disposizione degli organi sono predeterminati dal DNA. Gli scienziati giapponesi sono riusciti a manipolare questo sviluppo intervenendo sugli embrioni (di ancora otto cellule), inserendo sottilissimi bastoncini di vetro in modo da spostare alcune cellule obbligando il verso di sviluppo della spirale.
