Beware of eating oysters: here’s what could happen

L‘oyster (whose scientific name is ostrea) is a genus of bivalve mollusc that has a rounded shell covered with scaly and wavy gills. The two valves are not the same and the lower one, to which the animal is anchored, is much larger and hollow than the upper one. The mollusk has a rounded body, with the margins of the two edges fringed. Oysters live in all the seas of Europe with low depth, they live clinging to rocks and other solid bodies.

Who change sex according to the reproductive need of the moment; their eggs are contained in the palleal cavity of the female specimen, where fertilization and the maturation process take place (from the zygote to the larval stage).

After this period they release the progeny at the veliger stage, which then go through a pelagic phase of 8-10 days, during which they disperse from the water currents, thus causing the loss of medium-large quantities of the more mature molluscs. .
