The Spirographs are marine worms of the Sedentary Polychaeta class, belonging to the phylum of the Anellids. They live inside a tube of paper or calcareous consistency produced by the animal itself in which it withdraws in case of danger. The cephalic area is equipped with filiform gills covered with eyelashes and mucous glands, whose function is to pick up food particles. In fact it is a typical filtering animal that feeds on suspended plankton. intotheblue.it Spirografi vermi marini Policheti Sedentari phylum Anellidi

Much of the Mediterranean coast enjoys a hot-summer Mediterranean climate. However, most of its southeastern coast has a hot desert climate, and much of Spain’s eastern (Mediterranean) coast has a cold semi-arid climate. Although they are rare, tropical cyclone occasionally form in the Mediterranean Sea, typically in September–November.

Because of the short residence time of waters, the Mediterranean Sea is considered a hot-spot for climate change effects. Deep water temperatures have increased by 0.12 °C (0.22 °F) between 1959 and 1989. According to climate projections, the Mediterranean Sea could become warmer. The decrease in precipitation over the region could lead to more evaporation ultimately increasing the Mediterranean Sea salinity. Because of the changes in temperature and salinity, the Mediterranean Sea may become more stratified by the end of the 21st century, with notable consequences on water circulation and biogeochemistry.
