Large quantities of marine debris were found in the stomachs of sperm whales that washed up dead in Germany’s North Sea coast earlier this year.
The whales first surfaced in January and February near the coastal town of Tönning in the German state of Schleswig-Holstein. After officials ordered a necropsy of the bodies, post-mortem results were announced in a presentation at the Multimar Wattforum Centre on March 23.
Four of the 13 whales had large amounts of plastic waste in their stomachs, and some of the garbage included a 13-meter-long fishing net, a 70-centimeter-long plastic car engine cover and the remains of a plastic bucket, according to a press release from the Schleswig-Holstein Wadden Sea National Park.
“These findings show us the effects of our plastic society: Animals inadvertently take in plastic and other plastic waste and suffer, and at worst, starve with full stomachs,” environment minister Robert Habeck said in a statement (via Google Translate).
“This reminds us that we step up the fight against waste in the sea,” he said.
The whales were said to be all young bulls between the ages of 10 to 15 and weighed between 12 to 18 tons. Before surfacing in the shallow waters of the Wadden Sea in the North Sea, scientists suspected that the last time the whales had anything to eat besides plastic trash was in the Norwegian Sea.
According to the press release, male sperm whales in this population spend their winter in the North Atlantic but in their search for food, they mistakenly migrated to the food-poor North Sea.
Ursula Siebert from the Hanover Veterinary College told MailOnline she does not believe the whales died from consuming marine debris. Instead, she said that heavy storms in the north-eastern Atlantic pushed squid—the sperm whales’ main source of food—into the North Sea. She said the whales followed the squid into shallow waters before finally beaching on the shoreline.
As the Whale and Dolphin Conservation (WDC) explained, without support from the water, the sheer weight of the whales crushed their lungs and other organs, leading to death.

“Large amounts of plastic waste were also found in the stomachs of the sperm whales, including fishing nets, parts of a plastic bucket and even a plastic car cover. Although not the direct cause of death, vets suspect that the whales would soon experience major health problems as a result of this toxic waste,” the global conservation nonprofit said.
Since January, 29 sperm whales have washed up dead on the shores of Holland, Germany, France and the UK but it’s still unclear how the whales got into difficulty in the first place.
Whale strandings occur naturally, they can also be a result of man-made activity, such as noise from oil and gas exploration, pile driving into the sea bed to build wind farms, military sonar, or from entanglement in fishing gear and collision with boats, the Whale and Dolphin Conservation said in a blog post.
The Whale and Dolphin Conservation pointed out that there are more than 3,000 strandings worldwide every year, but not all of them have to end in tragedy.
The organization is working to prevent more strandings, including marine protected areas, preventing deaths and entanglements in nets, regulating boat traffic and helping to prevent collisions, and addressing pollution, including noise and sonar.
Have you heard the story of the sperm whales? And no I don't mean Moby Dick. Over the last few days 17 sperm whales have washed up in Germany, Holland and the UK. Why they've washed up, scientists aren't sure, but rumours of starvation, death by sonar and other awfully slow and painful methods of dying are included among the speculations. What we do know however, is that during an autopsy a 12 metre fishing net was found inside one individual. We do know that three of the whales were graffitied whilst lying on the beach. We do know that people posed for disturbing selfies with these magnificent creatures. We do know that we have not respected these creatures. Putting the cause of death aside, whether we were responsible for this tragedy or not, we have not shown respect to these whales. We have defaced them, exploited them, used them for our happy snaps and gossip. We have raped their bodies, stealing skin and teeth. This photo speaks a thousand words to me. It shows these mighty creatures, vulnerable and exposed in death, surrounded by tiny humans. This photo is reminiscent of ants to a corpse, not of one intelligent species mourning the loss of another. My favourite quote from Moby Dick sums up my feelings towards this image, "ignorance is the parent of fear". We ignore the damage we are doing. We ignore the pain of other creatures. We ignore these issues because we are scared. Scared that we cannot fix the damage we have caused and are continuing to do to this planet. So we turn a blind eye, we take a selfie to remember the moment, and we smile in it to try and distance ourselves from what we are really doing. Open your eyes. Look at what we have become as a species. Help be part of the change. #saveourseas #spermwhales #savethewhales #whale #marineconservation #marinescience #debris #plasticpollution #marinedebris #ocean #environment #sun7
