Tracking the fin whale and the sperm whale in the Mediterranean

Where are the great marine animals of the Mediterranean, such as the fin whale, the sperm whale or the bottlenose dolphin? How does their distribution change over a few weeks? All indications suggest that these species shift between marine areas in a remarkably short time and over relatively small spatial scales. Some species, such as the striped dolphin, maintain a relatively stable presence in certain areas, while others, such as the fin whale, move and concentrate in different areas from one observation campaign to the next.
