Common Remora

The Common Remora does not seem to have a negative overall effect on its host. The host provides the remora with fast-moving water to bathe its gills, a steady flow of food, transportation, and protection. The remora benefits the host by feeding in part on some of its parasites, but increases its hydrodynamical drag. Common Remora is commonly found in warm marine waters from all over the world.

Ghost Fishing Nets

The "ghost fishing nets" are a real problem for the entire marine ecosystem because they are made of nylon. A material that is not biodegradable: it can only be recycled following particular treatments and therefore creates significant pollution in the sea. Furthermore, as we have already said, it continues its fishing activity and therefore the killing of marine animals for many years.

Leopard Spotted-goby and European Lobster

During this dive I came across a strange pair of Mediterranean marine specimens. It is a European Lobster, Homarus gammarus, and a Leopard-spotted Goby that share the same cave; evidently there is a mutual convenience to which I cannot give a logical explanation. In fact, the European Lobster usually lives alone in the den that it has built and, in general, does not tolerate intrusions by others.

Special mission mediterranean Spiny Lobster

It is late August and Summer is the period in which many marine organisms prepare for procreation. We have therefore decided to reach a deep Mediterranean coral reef, over 7 miles from the coast. The procreation have pushed these crustaceans to gather at the same time and in the same place. Procreation, in fact, occurs at the end of the Summer and in the Winter the larvae are born, which immediately reach the seabed that will host them for the rest of their lives.

Often we fail to realize the quantity of different species that live next to each other and obviously it is almost impossible to know and recognize them all.
