Sexual Dimorphism

The Marbled Limpet Nerite Snail exhibits very little sexual dimorphism, with males and females appearing almost identical in size and physical characteristics.

While it can be challenging to distinguish between males and females based on their external appearance, it is possible to differentiate the two by observing their reproductive organs. Male snails have a small penis-like structure that is used to fertilise the eggs of female snails. Female snails, on the other hand, have a small genital opening through which the male's sperm can enter to fertilise their eggs.
