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.
