to be organized about the corals in the Pacific and Mediterranean. Among the species that are fished at high rates, are the Cephalopod family. These molluscans, especially the species O. Vulgaris, are of interest both for industrial and artisanal fisheries. Due to high biodiversity, productivity rates and importance of the different species for the ecosystem, the Mediterranean Sea and the Strait of Sicily are becoming of more interest for researchers during the recent years. Also regarding the current climate change, information can be gained by researching the changes in biodiversity in the Strait of Sicily. Volcanic activity Due to the natural position of the Strait of Sicily, above the conjunction of the Eurasian and African tectonic plate, volcanic activity occurs in the strait. The volcanic activity is mainly focused on the islands Pantelleria and Linosa. A climax in volcanic activity was found in the Pleistocene. Although minor submarine eruptions can still be found, mostly located on the seafloor along the northwest and southeast regional faults. During historical times some seamounts did erupt while other seamounts have been covered by Pliocene-Quaternary sediments. The submarine volcanoes are located in the Adventure Plateau, Graham and Nameless Banks. In 1831 a submarine volcano erupted on the Graham Bank at a depth of around 200 m. This eruption gave rise to the Graham Island 65 m above sea level. Also in the year 1863 this volcano erupted, whereas the youngest eruption in the region was in 1891 around 5 km north of Pantelleria. At the southeast of Graham Bank, at the Pinne Bank an emission was observed in 1941.
