I met the Pagurus of the short film, clinging to a gorgonian of Savalia Savaglia, at a depth of 78 meters. This particularly struck me because I never found a hermit crab at such depth despite my long experience of scuba diving. Paguro Pagurus Paguridi hermit crabs Savalia Savaglia intotheblue.it
The Pagurus belongs to the Paguridae family. Hermit crabs are crustaceans with a curved and soft abdomen. It lives in empty shells of gastropods on which it sometimes attacks sponges or poisonous actinias to camouflage and defend itself. In case of danger it can withdraw completely inside the shell. The end of the tail of the hermit crab is suitable for strongly grasping the shell it always carries with it. When it grows and the size of the shell is no longer suitable is search for a new shell to protect yourself.
In the world there are about five thousand known species, almost all of which live in the aquatic environment, but in the tropics there are also terrestrial ones. Paguro Pagurus Paguridi hermit crabs Savalia Savaglia intotheblue.it
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.
