Some oysters, mainly those that live in the eastern seas, produce beautiful pearls but they are also very popular in Mediterranean cuisine. Oysters are alternate sequential hermaphrodites, what does this mean? Who change sex according to the reproductive need of the moment; their eggs are contained in the pallial cavity of the female specimen, where fertilization and the maturation process (from the zygote to the larval stage) take place.
