Rope-entangled right whale spotted off coast of New England

The marine mammals are increasingly endangered as warmer waters push them into ship traffic and fishing gear

A North Atlantic right whale has been spotted entangled in rope off New England, worsening an already devastating year for the vanishing animals, federal authorities said.

Right whales number less than 360 and are vulnerable to entanglement in fishing gear and collisions with ships. The entangled whale was seen on Wednesday about 50 miles (80km) south of Rhode Island’s Block Island, the National Oceanic and Atmospheric Administration (NOAA) said.

Scientists find skull of enormous ancient dolphin in Amazon

Fossil of giant river dolphin found in Peru, whose closest living relation is in South Asia, gives clues to future extinction threats

Scientists have discovered the fossilised skull of a giant river dolphin, from a species thought to have fled the ocean and sought refuge in Peru’s Amazonian rivers 16m years ago. The extinct species would have measured up to 3.5 metres long, making it the largest river dolphin ever found.

The discovery of this new species, Pebanista yacuruna, highlights the looming risks to the world’s remaining river dolphins, all of which face similar extinction threats in the next 20 to 40 years, according to the lead author of new research published in Science Advances today. Aldo Benites-Palomino said it belonged to the Platanistoidea family of dolphins commonly found in oceans between 24m and 16m years ago.

Gray whale sighted off New England 200 years after species’ Atlantic extinction

Scientists confirm cetacean’s presence but cite impact of climate change which has made North-west Passage ice-free in summer

Scientists have confirmed the presence of a whale off New England that went extinct in the Atlantic Ocean two centuries ago – an exciting discovery, but one they said that illustrates the impact of climate change on sea life.

Researchers with the New England Aquarium in Boston found the gray whale while flying 30 miles south of Nantucket, Massachusetts, on 1 March. The whale, which can weigh 60,000 pounds (27,215kg), typically lives in the northern Pacific Ocean.

Bolsonaro under investigation for ‘harassing’ humpback whale

Man resembling Brazilian ex-president seemingly spotted on a jetski about 15 metres from distressed mammal

Federal police are investigating Brazil’s former president, Jair Bolsonaro, for yet another suspected misdeed: “harassing” a humpback whale while taking a public holiday spin on his jetski.

Bolsonaro’s anti-environmental policies earned him the nickname “Captain Chainsaw” during a four-year administration characterised by soaring destruction of the Amazon. But the far-right ex-president’s latest suspected environmental offence reportedly occurred in the waters off Brazil’s south-eastern coastline near the town of São Sebastião.

Newly discovered whale species could have been heaviest animal ever

Fossils found in Peru from extinct species show it may have had body mass of 85-340 tonnes – heavier than blue whales

The fossilised bones of an ancient creature that patrolled coastal waters 40m years ago belong to a newly discovered species that is a contender for the heaviest animal ever to have existed on Earth.

Fossil hunters discovered remnants of the enormous and long-extinct whale in a rock formation in the Ica desert of southern Peru. Fully grown adults might have weighed hundreds of tonnes, researchers believe.

Australia news live: rental pressure ‘most concerning’ aspect of inflation picture, Jim Chalmers says

Follow live news updates today

The minister for sport and aged care, Anika Wells, says her focus is on people in sport, not the infrastructure, following the announcement Victoria was pulling out of hosting the Commonwealth Games.

Wells has told ABC Radio she was not warned by Victorian premier, Daniel Andrews, ahead of time about the decision, and found out along with the rest of the country when he stood up to make the announcement.

I care for our athletes. I think that that dream of competing on home soil for your country is one of the most potent dreams that motivate our high performance athletes and possibly our kids as well to go from from playground to podium.

But given how many events that Australia does already have on the green and gold runway and the World Cups – we’re hosting four Women’s World Cups across the next five years, including the one that is on right now – as long as we have opportunities for people to go from playground to podium.

Governments continue to make decisions that disregard or contradict the Agreement.

… Overall progress against the priority reforms has been slow, uncoordinated and piecemeal.

Here is potential for the proposed Voice to the Australian Parliament (as well as state and territory representative bodies), together with current treaty processes and justice commissions, to strengthen accountability for matters covered by the Agreement.

But regardless of the outcomes of these processes, governments will still be responsible for adopting a fundamentally new way of developing and implementing policies and programs that affect Aboriginal and Torres Strait Islander people, as they have committed to do in the Agreement.

Grey whales seen seeking human help to remove parasites

Captain of tourist boat from Baja California, Mexico, says grey whales return repeatedly for ‘grooming’

Grey whales have learned to approach whale-watching boats to have parasites removed by human beings, it has been claimed.

Video footage documenting the behaviour in the Ojo de Liebre lagoon, off the coast of Baja California, Mexico, shows a grey whale having whale lice picked off its head by the captain of a small boat. “I have done it repeatedly with the same whale and others,” Paco Jimenez Franco told a US news site. “It is very exciting for me.”

Myroshnychenko says Ukraine war can’t get any worse

On the mutiny by Yevgeny Prigozhin and his wagner mercenary group, Myroshnychenko says he is reluctant to get into speculation about “palace intrigue” in Russia.

We haven’t seen any major impact in the battlefield as the mutiny was unfolding, Russians sent on shelling Ukrainian cities sending missiles, heavy battlefields on the frontlines. Definitely the reputation of Vladimir Putin was dented. His leadership was challenged. And in a country like Russia is really extraordinary to see it happening. Putin is running the country as a thug so pretty much a gangster country and all these thugs and somebody revolts all of a sudden, this is already kind of bizarre.

I don’t think anything can be worse, right? Can it get any worse? Look, Russians have deployed 150,000 people in Ukraine – occupied 20% of the land. They just shell us on a continuous basis, killing and raping and murdering people. Can it get any worse? I don’t think so.

I think any support for Ukraine will be very good investment into the restoration of the rules-base international system.

Something which is so important for every Pacific nation because if you can allow a bigger power to curse a smaller power – and you don’t fight back and you let that happen, that sends a wrong signal especially to your neighbours, to countries that depend so much on your support to be sovereign and to make their own decisions and not to be influence bid bigger powers.

Skin disease in orcas off North American coast concerns scientists

Lesions found on 99% of southern resident orcas studied on Pacific north-west coast

Scientists studying an endangered population of orcas resident off the Pacific north-west coast of Canada and the US have recorded a “strong increase” in skin lesions on the animals’ bodies, which they believe is owing to the decreasing ability of their immune systems to deal with disease.

The lesions appear on the whales as grey patches or targets, or black pin points. Some resemble tattooed skin. Their presence on the animals’ graphically black and white bodies is “increasing dramatically”, according to Dr Joseph K Gaydos of the SeaDoc Society at the school of veterinary medicine at the University of California, lead author of the scientific paper.
