Pilot whales are already 'shouting' at full volume, but one busy waterway is pushing them to the edge

With over 60,000 ships passing through the Strait of Gibraltar each year, this stretch between the Atlantic and Mediterranean is one of the busiest waterways on the planet. This narrow strip of water is also home to a critically endangered population of long-finned pilot whales (Globicephala melas). Living in such congested waters, whales must thread their way between vessels while attempting to catch food, find mates and raise their young.
