Whale

Led by the sounds of mysterious acoustic signals, a group of beaked whale experts believe they have captured evidence of an entirely new species, sending chills up their spines as they ponder the existence of a completely unknown large mammal.

After an almost complete absence for 50 years, blue whales are returning to the waters surrounding South Georgia island in the south Atlantic. A study has collected 58 sightings of the giant cetaceans as well as acoustic soundings of their presence.

A new study has delved into underwater behavior of remora, producing the first-ever continuous recordings of these so-called suckerfish in action and showing how they surf, feed and even socialize on the surface of blue whales.

Sperm whales use echolocation to search for prey in the dark ocean – so it makes sense that competing sounds could screw that process up. A recent study now indicates that even a new-and-improved type of manmade sonar does indeed cause problems.

A recent study led by scientists from Australia's New Curtin University shows that the world's smallest type of killer whale, the Ross Sea killer whale, has a surprisingly complex musical repertoire with 28 different complex calls.

Grey whales may be "blinded" by solar storms, according to a new study. The solar activity interferes with the whales’ internal magnetic navigation system, causing them to become stranded on the shore, often resulting in death.

A new survey led by the British Antarctic Survey (BAS) indicates that blue whales and other large whale species are making a welcome comeback in waters off South Georgia, with 55 of the critically endangered whales spotted in 2020.

Scientists at Stanford University have found that the humpback whale, which weighs in at about 30 tonnes, uses stealth and deception to get within lunging distance of the schools of anchovies and other fish on which it feeds.

The ancestors of today's whales originally walked on four legs. New research suggests that previously-discovered fossils represent a point at which the creatures were moving from swimming with those legs to swimming with their tails.

A team of Stanford University scientists have captured the first ever recording of a blue whale’s heart rate, and in doing so, have gathered some interesting insights into the massive mammal's behavior and evolution.

As far as fighting climate change is concerned, "one whale is worth thousands of trees," the IMF has said. But reports suggesting that trees therefore pale into insignificance compared to whales are missing the point.

Scientists have used a drone to calculate the weight of live whales as they're swimming.
