Whale

Omnidirectional video cameras are becoming increasingly popular, although they're still mostly just used recreationally. A scientific research team, however, has now utilized one of the devices to gain a better understanding of whale behaviour.

Just like a tree trunk, the tusk of the narwhal acquires a new growth ring every year. Analyses of those rings have now revealed some interesting facts about the animals' diet, and about changes in their environment.

Oregon State University researchers have found that fin whale songs interact with the ocean floor, being reflected and refracted by the sediments and bedrock, and can be used to measure the thickness of these layers as well as providing other data.

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.
