SOCR Data - Sexual Dimorphism in Snails

Study Description

edit
 
Cocholostoma septemspirale

This study measured differences between the shells of the snail species Cochlostoma septemspirale. By observing multiple traits of the shells, the researchers were able to decide on a series of dimorphisms (difference in forms) between male and female snails
