Bowhead whales dive in synchronization despite distances of up to 100 kilometers between them, according to a study by Danish, Greenlandic and Japanese researchers. This shows that the whales use an advanced form of acoustic communication, according to Danish researcher Jonas Teilmann, professor at Aarhus University. “It involves hundreds of dives over a week that […]
I was really happy with my task, staying on the surface. I truly wanted to snorkel with dolphins, but the sharks made me hesitate. Finally, Joel convinced me to join him. It was so cool to see everything from below, and I finally got to snorkel with dolphins! But it was the whales that made this day unforgettable.
In the midst of the chaos of sardines, dolphins, birds and sharks there appeared a lonesome Humpback whale. She seemed not to be concerned with the frenzy which ensued around her but rather quite intrigued by the shoal of sardines which seeked refuse under her enormous shadow.
The narwhal is a relatively small arctic toothed whale (4 - 5 meters). It is shy and typically lives in the drift ice around the northern ice cap, where it can live up to 100 years. This makes the narwhal particularly vulnerable to the severe climate changes that are taking place around the Arctic. The Inuit have traditionally hunted narwhals both for their valuable tusk, fine meat and not least, for the tasty skin.
In part two, we delve into the threats facing the small-toothed whales that inhabit Sweden's waters. Why are these porpoises becoming increasingly rare, and what steps can we take to address the issue?
Sweden's only whale is not easy to see. In the Baltic Sea it is acutely threatened, but outside Kullaberg there is a small colony. There, scientists try to learn more about the porpoise's secret life. With the help of new technology, it can be studied both from above and below the water's surface.
Blue whales ingest up to 10 million pieces of microplastics per day, according to estimates in a study. This suggests that the pollution poses a greater danger to the world's largest animals than previously thought
Researchers in Argentina are concerned that several whales have been found dead in the south of the country. They believe a microalgae may be behind the deaths. Between 24 September and 2 October, at least 13 southern capemen have died in a water area near the Valdés Peninsula, an area that is a haven and breeding ground for the
It has been known for some time that humpback whales can communicate over great distances. The song is carried along during the humpback whale's long migrations across the oceans and researchers have now seen how local songs have migrated further across the Pacific - from the coast of Australia all the way to Ecuador, reports Vetenskapsradion.
We are going to the northern Norwegian fjord Kvänangen approximately 20 miles north of the Arctic Circle. Fishing boats from all over the Norwegian west coast come to this particular fjord during some intense winter months to fish huge amounts of herring. But there are also other creatures that want the herring. In addition to a number of predatory fish and gulls, an unusually high number of killer whales and large humpback whales have also become increasingly numerous. Sometimes there may be conflict
Whales, with their majestic appearance, enthrall most people, but human activity in the oceans makes it increasingly difficult for animals. Now the World Wildlife Fund (WWF) is pulling the emergency brake, requiring special whale protection areas for the routes whales migrate along
The Swedish Museum of Natural History has released a new report showing that the porpoise population in the Baltic Sea may be recovering. The porpoise, the Baltic Sea's only whale, is critically endangered and today only 500 individuals remain
