Whales, as we all know, are different from most other sea creatures. They are mammals, and give birth to live babies… and then they nurture and raise those babies, nursing them on rich, fatty milk so they can grow big and strong. But we can’t just put whales in an aquarium and watch them raise their families. They are large beasts with complex societies, and their migration can take them around the world.

While the ocean isn’t exactly hospitable to humans, though, we can send our technology. Through the use of whale-mounted cameras, scientists from the University of Hawaiʻi, Stanford University, and UC Santa Cruz were able to capture breathtaking video of humpback whales nursing their calves as they wintered in their breeding grounds in Maui.

Every year, around 10,000 humpback whales r...

Sometimes it feels like we know all there is to know about the natural world. But when you talk to researchers in biology, ecology, geology or other science subjects, they’ll tell you what we know only scratches the surface. There’s so much more to discover. In the animal world, whale migration is a great example.

Thus far, marine biologists have never been sure why whales migrate. They hypothesized that it had something to do with where they prefer to give birth (many whales calve in warmer waters), or maybe was connected with food supplies. But whales are large enough animals that the cold waters where they tend to live should be fine for giving birth, and during migration, whales eat a lot less because they’re busy moving and not finding hunting grounds.

But there’s a new theory: Maybe ...

Scientists say they have seen a remarkable collection of blue whales in the coastal waters around the UK sub-Antarctic island of South Georgia. Their 23-day survey counted 55 animals – a total that is unprecedented in the decades since commercial whaling ended. South Georgia was the epicentre for hunting in the early 20th Century.

The territory’s boats with their steam-powered harpoons were pivotal in reducing Antarctic blues to just a few hundred individuals.

To witness 55 of them now return to what was once a pre-eminent feeding ground for the population has been described as “truly, truly amazing” by cetacean specialist Dr Trevor Branch from the University of Washington, Seattle.

“To think that in a period of 40 or 50 years, I only had records for two sightings of blue whales around S...

A great whale is worth US$2 million (NZ$3.1 million). The size of that number so terrified Ralph Chami, the economist who appraised the whales, that he sought refuge in a church for the first time in 30 years. Inside St. Matthew’s Cathedral here, a few blocks from Chami’s office at the International Monetary Fund, the economist said he had “a conversation with the Maker. I said: ‘If you aim to humiliate me, there are other ways of doing it.’ “

Chami had, after all, veered outside his lane to make a first-of-its-kind claim. He studies macroeconomic policies in developing countries, not ecology...

A baby sperm whale found washed-up on a beach in Wales had plastic sheeting and other marine rubbish in its stomach, experts have said. The 22-foot long male calf washed up near Abersoch, Gwynedd, on Tuesday and is the first sperm whale to wash up on the Welsh coast in over 100 years. A post-mortem examination found that the animal was malnourished and below a healthy weight.

Experts from the Cetacean Strandings Investigation Programme and the Zoological Society of London (ZSL) who conducted the post-mortem were perplexed as to how it had found its way to such shallow waters given the species generally lives in deeper southern waters which are hotter and where they feed on giant squid.

Rob Deaville, of the ZSL, said: “A large piece of blue plastic sheeting was found in the stomach and ...

When it comes to saving the planet, one whale is worth thousands of trees. Scientific research now indicates more clearly than ever that our carbon footprint – the release of carbon dioxide (CO₂) into the atmosphere where it contributes to global warming through the so-called greenhouse effect – now threatens our ecosystems and our way of life.  But efforts to mitigate climate change face two significant challenges.  The first is to find effective ways to reduce the amount of CO₂ in the atmosphere or its impact on average global temperature.  The second is to raise sufficient funds to put these technologies into practice.

Many proposed solutions to global warming, such as capturing carbon directly from the air and burying it deep in the earth, are complex, untested, and expensive...

JAPAN will begin hunting whales for commercial purposes next month for the first time in more than 30 years after pulling out of the International Whaling Commission (IWC).

Five vessels will set off from six different whaling operators on July 1 in the first commercial whaling operation since 1986. Japan joined the global body for the conservation of whales in 1982, ceasing operations four years later. But the country had continued to hunt between 200 and 1,200 whales each year for scientific reasons, selling the meat on afterwards for consumer purposes. 

Eating whale is seen to be part of Japanese culture even though consumption has fallen dramatically since the 1960s. 

Pro-whaling nations expected the IWC to be a temporary measure until a sustainable catch quota was formed but ...

Whales may be largest animals on Earth, but that still doesn’t mean they’re easy to find in the vast oceans they inhabit. In the past, researchers have used acoustic monitoring, aerial surveys and binoculars to keep track of the marine mammals. Each of those techniques, however, can only survey a tiny slice of the oceans. Jonathan Amos at the BBC reports that a new study shows whales can be counted from space, giving conservationists a massive new tool to survey and monitor to creatures.

Researchers have tried to count whales using satellite imagery in the past with limited success since the resolution just wasn’t fine enough. For the new study in the journal Marine Mammal Science, researchers from the British Antarctic Survey and the University of Cambridge gave it another shot, usi...

A fleet of Japanese whaling ships caught 177 minke and sei whales during a three-month tour of the northwestern Pacific, the government said Wednesday. The three-ship mission returned home as Tokyo prepares to make its case to resume commercial whaling at a meeting of the International Whaling Commission (IWC) in Brazil next month.

During the latest 98-day mission, the ships caught 43 minke whales and 134 sei whales, the Fisheries Agency said in a statement.

Foreign pressure on Japan to stop whaling has only made conservatives and politicians more resolute about continuing their push to resume commercial whaling.

It is a rare thorny issue in Tokyo’s otherwise amiable diplomacy.

“Data that were gathered during this mission will be analysed, along with results from coastal research programm...

Whale enthusiasts are celebrating the return of the humpback to B.C.’s coastal waters, even though it means people need to learn how to coexist with the gentle giants. The Northeast Pacific population of humpback whales, which spend much of their time in B.C. waters during the summer months, has experienced a remarkable recovery in the past few decades.

The migratory whales, known for their underwater ballads, are easily recognizable by their long pectoral fins and knobby heads.
