Arbacia lixula
 The Black Sea Urchin Arbacia lixula is a Sea Urchin found on the coast of the Mediterranean Sea and Macaronesian Islands (Azores Madeira Canary Islands) and less commonly on the Atlantic coast of Western Africa and the Brazilian coast. It is found typically at shallow waters at depths from 0 to 30 m in rocky shores. It has a good resistance to hydrodynamism due to a good attachment strength to rocks.
