Mussels - Mytilus galloprovincialis

This stamp from the “Marine Fauna” series presents the Mussels, a bivalve mollusc very common on the rocky coasts of northern Tunisia. Sadok Ben Yacoub's illustration shows a cluster of mussels with bluish reflections attached to their support.

This stamp highlights the country's fishing resources. The mussel is not only a key element of coastal biodiversity but also an important economic resource, particularly through shellfish farming practiced in Lake Bizerte.
