The search for the loneliest whale in the world

When people learned he vocalized at a much higher pitch than other whales, they wondered: could other whales hear him? Was he plaintively calling, never hearing a reply? Was he lonely?

The loneliest whale in the world lives in the north Pacific. Scientists have been tracking him on and off for more than 30 years – listening to his vocalizations as he swims back and forth across his patch of ocean, calling into the void and waiting for a reply that never comes. That’s the story, anyway. The makers of a new documentary set out to find the truth – and the whale – but what they discovered is that a whale struggling to be heard may not be that unusual at all.

The tale has its origins in the cold war, when the US military deployed a network of hydrophones across the ocean floor to listen for Soviet submarines. In the process, operators also picked up unexpected background noises, including a series of strange, low-frequency moans initially attributed to an unknown “Jezebel Monster” but later identified as the deep, rumbling calls of blue and fin whales. By the end of the 1980s, with the cold war spluttering to an end, the Pentagon made the network available to whale researchers. Among them was William Watkins, a pioneer in identifying and tracking marine mammals by the sounds they make.

Goldfish dumped in lakes grow to monstrous size, threatening ecosystems

Minnesota pet owners warned not to release fish into wild, where they wreak havoc on native species

Authorities in Minnesota have appealed to aquarium owners to stop releasing pet fish into waterways, after several huge goldfish were pulled from a local lake.

Officials in Burnsville, about 15 miles south of Minneapolis, said released goldfish can grow to several times their normal size and wreak havoc on indigenous species.

‘I’d let you bite me!’ Shark Beach With Chris Hemsworth is dangerously flirty TV

Never mind that the Hollywood star has never encountered a great white – this documentary has Thor, his perfect jawline … and flirting so full-on it could crack the camera lens

There are only three reasons why you would watch the new documentary Shark Beach With Chris Hemsworth: you love sharks, beaches or Chris Hemsworth. Hopefully it’s the latter, because that’s clearly what the producers have anticipated.

The opening scene sees the Hollywood actor gazing out to sea at sunrise, surfboard under his arm, blue-steeling the horizon. “There’s nothing quite like the ocean at first light,” he murmurs, as if auditioning for an aftershave commercial. Waves crash. Hemsworth smoulders. A didgeridoo blows.

Record number of manatees die in Florida as food source dries up

State officials report ‘unprecedented’ deaths due to starvation as pollution and algal blooms take toll

More manatees have died already this year than in any other year in Florida’s recorded history, primarily from starvation due to the loss of seagrass beds, state officials have said.

The Florida Fish & Wildlife Conservation Commission reported that 841 manatee deaths were recorded between 1 January and 2 July, breaking the previous record of 830 that died during the whole of 2013 because of an outbreak of toxic red tide.

‘Heat dome’ probably killed 1bn marine animals on Canada coast, experts say

British Columbia scientist says heat essentially cooked mussels: ‘The shore doesn’t usually crunch when you walk’

More than 1 billion marine animals along Canada’s Pacific coast are likely to have died from last week’s record heatwave, experts warn, highlighting the vulnerability of ecosystems unaccustomed to extreme temperatures.

The “heat dome” that settled over western Canada and the north-western US for five days pushed temperatures in communities along the coast to 40C (104F) – shattering longstanding records and offering little respite for days.

‘Killing spree’: Wisconsin’s wolf population plunges after protections removed, study finds

Researchers blame poaching and hunting far beyond quotas after species dropped from endangered list

As many as one-third of Wisconsin’s gray wolves probably died at the hands of humans in the months after the federal government announced it was ending legal protections, according to a study released on Monday.

Poaching and a February hunt that far exceeded kill quotas were largely responsible for the drop-off, University of Wisconsin scientists said.

Climate crisis causing male dragonflies to lose wing ‘bling’, study finds

Black patterns used to attract mates can cause the insects to overheat in hotter climates

Male dragonflies are losing the “bling” wing decorations that they use to entice the females as climates get hotter, according to new research.

The results have led to the scientists calling for more work on whether this disparate evolution might lead to females no longer recognising males of their own species in the long run.

Mammoth journey ahead as elephants leave Kent zoo for the Kenyan savannah

All but one of the herd of 13 were born in captivity, but conservationists hope they can be ‘rewilded’


A herd of elephants born and raised in a Kent zoo are about to get on a plane to travel almost 4,500 miles (7,000km) to Kenya, in order to reintroduce them to the wild in a first-of-its kind operation.

The herd of 13, which includes three calves, were all but one born at Howletts Wild Animal Park, a private zoo near Canterbury. The mammoth mission to “rewild” the elephants is being carried out by the Aspinall Foundation, the Kenya Wildlife Service and Sheldrick Wildlife Trust.

A drop in the ocean: rewilding the seas

From giant clams to zebra shark, marine biologists want to replace lost and vanishing species at sea but face unique obstacles – not least rampant overfishing

Kneeling on the seabed a few metres underwater, I pick up a clam and begin gently cleaning its furrowed, porcelain smile with a toothbrush. It’s a giant clam but a young one and still just a handful. Here in Fiji, giant clams or vasua as they are known, were so heavily overfished for their meat and shells that by the 1980s they were thought to be extinct locally. Australian clams were imported to start a captive breeding programme, and subsequent generations of their offspring have been released on coral reefs across Fiji. They’re still vulnerable to fishing and poaching, but if carefully guarded the giant clams do well and have become symbols of healthy corals reefs inside well-managed marine protected areas.

A key to their early survival is rearing them in cages to keep them safe from predators until they’re large enough to survive by themselves. However, the cages also exclude herbivorous fish, so the clams can easily get overgrown by seaweed, which is where the regular toothbrushing comes in.

Not a lone shark: bull sharks may form ‘friendships’ with each other, study finds

The apex predators show preferences for certain individuals and avoid others, according to new research on sharks in Fiji

They reach 3.5 metres long, weigh more than 200kg and are an apex predator. But even apex predators need friends. And, according to new research, bull sharks may be capable of making them.

A recently published study from Fiji shows that bull sharks develop companionships – with some sharks showing preferences for certain individuals and avoiding others.

Damaging ‘fly-shooting’ fishing in Channel sparks concerns

Small-scale fishers say mostly EU fleet is devastating catches with method that nets entire shoals of fish

The UK has been accused of allowing a fleet of mainly EU “fly-shooting” fishing boats “unfettered access” to the Channel, without a proper assessment of the impact on fish populations, the seabed or the livelihoods of small-scale fishers.

Organisations representing small-scale fishers on both sides of the Channel have warned that the fleet is having a “devastating” effect on their catches. They are calling for a review of the vessels’ UK licences until an impact assessment has been carried out.

Where the buffalo roam: world’s longest wildlife bridge could cross the Mississippi

Conservationist aims to replace old bridge with bison preserve, benefiting environment and spotlighting Indigenous history

Between Iowa and Illinois, spanning the only stretch of the Mississippi River that flows from east to west, sits an exhausted 55-year-old cement bridge. Each day 42,000 cars drive across the ageing structure, which is slated to be torn down and replaced.

But when Chad Pregracke looks at the bridge, he has a different vision entirely – not an old overpass to be demolished, but a home for the buffalo to roam.

The real urban jungle: how ancient societies reimagined what cities could be

They may be vine-smothered ruins today, but the lost cities of the ancient tropics still have a lot to teach us about how to live alongside nature

Visions of “lost cities” in the jungle have consumed western imaginations since Europeans first visited the tropics of Asia, Africa and the Americas. From the Lost City of Z to El Dorado, a thirst for finding ancient civilisations and their treasures in perilous tropical forest settings has driven innumerable ill-fated expeditions. This obsession has seeped into western societies’ popular ideas of tropical forest cities, with overgrown ruins acting as the backdrop for fear, discovery and life-threatening challenges in countless films, novels and video games.

Throughout these depictions runs the idea that all ancient cities and states in tropical forests were doomed to fail. That the most resilient occupants of tropical forests are small villages of poison dart-blowing hunter-gatherers. And that vicious vines and towering trees – or, in the case of The Jungle Book, a boisterous army of monkeys – will inevitably claw any significant human achievement back into the suffocating green whence it came. This idea has been boosted by books and films that focus on the collapse of particularly enigmatic societies such as the Classic Maya. The decaying stone walls, the empty grand structures and the deserted streets of these tropical urban leftovers act as a tragic warning that our own way of life is not as secure as we would like to assume.

Elephant in the room: visitor crashes through kitchen wall in Thailand

Woman finds hungry elephant rummaging for late-night snack – and it’s not the first time he’s stopped by

Ratchadawan Puengprasoppon was awoken in the early hours of Saturday morning by crashing and banging. When she went to find out what had happened, she discovered an elephant’s head poking through her kitchen wall beside the drying rack.

The male elephant, named Boonchuay, appeared to be looking for something to eat. His trunk rummaged through the kitchen drawers, knocking pans and cooking paraphernalia to the floor. He chewed on a plastic bag as Ratchadawan, unsure what to do, filmed the episode on her phone.

Tasmanian devils wipe out thousands of penguins on tiny Australian island

Marsupials introduced to Maria Island, east of Tasmania, to safeguard their numbers but have decimated birdlife

An attempt to save the Tasmanian devil by shipping an “insurance population” to a tiny Australian island has come at a “catastrophic” cost to the birdlife there, including the complete elimination of little penguins, according to BirdLife Tasmania.

Maria Island, a 116-square-kilometre island east of Tasmania, was home to 3,000 breeding pairs of little penguins around a decade ago.

Bee-friendly urban wildflower meadows prove a hit with German city dwellers

Countrywide scheme is flourishing after being set up to reverse a 75% decline in insect populations

To escape the Berlin bustle on a summer afternoon, all that Derek O’Doyle and his dog Frida have to do is lap the noisy building site outside their inner-city apartment, weave their way through the queue in front of the ice-cream van, and squeeze between two gridlocked lorries to cross over Baerwaldstrasse.

Bordered by a one-way traffic system lies a bucolic 1,720 sq metre haven as colourful as a Monet landscape: blue cornflowers, red poppies, white cow parsley and purple field scabious dot a sea of nettles and wild grass as armies of insects buzz through the air. Two endangered carpenter bees, larger than their honey bee cousins and with pitch-black abdomens, gorge themselves on a bush of yellow gorse.

The whale sentinel: two decades of watching humpback numbers boom

After more than 20 years watching from the cliffs of Botany Bay, Wayne Reynolds’ passion is having tangible results

He may have seen it tens of thousands of times before but when Wayne Reynolds spots a whale emerging from the water, he reacts with the excitement of a child pointing out a rollercoaster at an amusement park.

“Oh wow, there’s a minke and her calf,” he yells out with boyish enthusiasm from the rocky cliff at Potter Point in Kurnell, in Sydney’s south. “I just go into auto-mode, I can’t help it.”
