There may be a little more evidence to suggest that Neanderthals waded, swam, and even dove to gather resources along the shores of the Mediterranean. A new study claims Neanderthals at a coastal cave in Italy waded or dove to get clamshells straight off the seafloor to make scraping tools.
Neanderthals who lived at Grotta dei Moscerini around 100,000 years ago used the sturdy shells of Mediterranean smooth clams to make sharp-edged scraping tools. Clamshells wash up on beaches all the time, but University of Colorado archaeologist Paola Villa and her colleagues say that some of the worked shell tools at Moscerini look less like flotsam and more like someone scooped them off the seafloor while they were still fresh.

If Villa and her colleagues are right, Neanderthals at Moscerini may have practiced free diving, and they certainly did a lot of wading. Mediterranean smooth clams usually live in at least half a meter (1.6 feet) of water, and usually more. They bury themselves just beneath the sand, and it’s easy to spot where their feeding siphons reach up to the water above. Neanderthals could have easily scooped them up by hand if they were willing to go deep enough.
Members of the hominin family tree have used shells to cut and scrape things for at least 430,000 years, when Homo erectus groups on the shores of Java used freshwater mussel shells as tools. Even after agriculture reached most of Europe during the Neolithic period around 9,000 years ago, people still used mussel shells to clean hides and finish the surfaces of ceramic vases. But usually, people just picked shells up and used them, without any kind of reworking to make them better tools. Moscerini is one of the only known sites were people were working shells into a particular sharp-edged shape, as if it were flint.

At Moscerini 23.9% of the specimens were gathered directly from the sea floor as live animals by skin diving Neandertals.
Archaeological data from sites in Italy, France and Spain confirm that shell fishing and fresh water fishing was a common activity of Neandertals, as indicated by anatomical studies recently published by E. Trinkaus. Lithic analysis provides data to show the relation between stone tools and shell tools. Several layers contain pumices derived from volcanic eruptions in the Ischia Island or the Campi Flegrei (prior to the Campanian Ignimbrite mega-eruption). Their rounded edges indicate that they were transported by sea currents to the beach at the base of the Moscerini sequence. Their presence in the occupation layers above the beach is discussed. The most plausible hypothesis is that they were collected by Neandertals. Incontrovertible evidence that Neandertals collected pumices is provided by a cave in Liguria. Use of pumices as abraders is well documented in the Upper Paleolithic. We prove that the exploitation of submerged aquatic resources and the collection of pumices common in the Upper Paleolithic were part of Neandertal behavior well before the arrival of modern humans in Western Europe.
