This marine species lives on the seabed, on the coasts of the northern Adriatic Sea. They are able to live anchored to the rocks at a depth of 40 metres, or resting on the mud. They generally live in groups and are bred. Their pulp contains a low composition of unsaturated fats but at the same time a large amount of protein, ensuring a favourable nutritional intake. Being gluten-free, it is recommended in the diet of those with celiac disease. They are harvested and eaten throughout the year, principally between October and April.
