In disaster-prone Vanuatu, photos show sea animals returning to battered reefs. Can recovery happen?
For the past decade, the South Pacific island nation's coral reefs have faced one punishing blow after another. Cyclone Pam in 2015 hit from a direction that left one reef particularly exposed.
'The way the waves came in actually smashed the coral,' said John Warmington, a longtime resident of Vanuatu who's been diving the reef for more than 10 years. 'I can remember our first dive after the cyclone and my friends and I were all in shock. Coral heads turned over, smashed staghorns — all laid bare.'
In the days that followed, heavy rains washed sediment into rivers that emptied into the sea, blanketing corals in a thick debris that blocked the sunlight they need to survive.
Other threats followed. Crown-of-thorns starfish — natural coral predators whose populations can surge after heavy rains wash nutrients into the sea — swept in to devour what remained. Though native to the region, they can multiply into outbreaks that decimate hard corals, especially vulnerable species like staghorns and plate corals. In 2023, two cyclones struck within days of each other, flattening swaths of reef that had just begun to regrow. And in December 2024, a 7.3-magnitude earthquake shook the seafloor.
'The whole reef slid down into the deep like an underwater landslide,' Warmington said. 'We just saw heartbreak.'
Vanuatu, which is home to about 300,000 people spread across 83 islands, is among the countries most vulnerable to climate change. Here, rising seas and saltwater intrusion are reshaping coastlines and disrupting daily life. Since 1993, sea levels around Vanuatu's shores have risen by about 6 millimeters (.24 inches) per year — significantly faster than the global average — and in some places, tectonic shifts have doubled that pace.
Despite all the disaster and hardships, some shallows are bouncing back. Clownfish take refuge inside anemones. Schools of silver mono fish flicker in the sun. A kaleidoscope of hard and soft corals have begun to root themselves to the reef once again.
Still, in one of the world's most disaster-prone regions, that recovery remains fragile.
'We're seeing new corals coming through, but do they get a chance to actually grow before another insult comes and damages them?' said Christina Shaw, CEO of the Vanuatu Environmental Science Society, a local NGO. 'Whether that's overfishing, crown-of-thorns, man-made pollution, or increased runoff from natural disasters — the insults to our marine system keep coming. And I think that's why our reefs might well be in trouble.'

Worst coral bleaching on record for Western Australian reefs
World-famous coral reefs along Western Australia's (WA) coast have suffered the worst bleaching on record after the state's "longest, largest and most intense" marine heatwave, scientists last August and this May, warmer water temperatures led to significant heat stress on the reefs, causing many of the coral to expel the algae which gives them life and colour - a process called bleaching, which is often damage - which will take months to assess - spans 1,500km (932 miles) and includes areas previously unscathed by climate reefs worldwide have been suffering from a two-year-long global coral bleaching event, due to record high ocean temperatures. Eight weeks of heat stress is usually enough to kill coral, and early estimates showed many WA reefs suffered between 15 and 30, said Australia's marine science agency. "The length and intensity of the heat stress, and its footprint across multiple regions, is something we've never seen before on most of the reefs in Western Australia," James Gilmour, from the Australian Institute of Marine Science (Aims), a new report, the Aims researchers found the 2024-25 season was the "most severe coral bleaching on record" for WA coral reefs across both the northwestern and central reefs."Areas which had given us hope because they'd rarely or not bleached before - like the Rowley Shoals, north Kimberley and Ningaloo - have been hit hard this time. Finally, climate heating has caught up with these reefs," he said. Climate change means bleaching events are becoming more frequent, more intense and more widespread, which Dr Gilmore says gives coral reefs - which need 10 to 15 years to recover - little time to bounce back."Climate change caused by carbon emissions remains the greatest threat to our coral reefs, and all reefs globally," he said.

Morecambe Bay: Volunteers find 18,000 shark egg cases on beaches
Volunteers who survey shark eggs in Morecambe Bay counted nearly 18,000 egg cases last Wildlife Trust's The Bay Group have earned a national award for the findings, being recognised at the Marsh Volunteer Awards for Marine volunteers search for old egg cases on the shoreline, take photographs of them, and upload them to the Shark Trust's Wright from Lancashire Wildlife Trust said: "I don't think people realise what we've got in the Irish Sea. We've got things like dolphins, porpoises, giant basking sharks, humpback whales." "The Irish Sea is such an important place and we really need to protect it," he told BBC Radio cases protect the embryos of sharks and skates as they develop. Once empty, they often wash up on beaches. The Morecambe Bay group found 30% of all egg cases across the UK last cases are rehydrated, categorised and counted - which helps scientists understand the population make up of our data showed that the small-spotted catshark and the thornback ray were the most commonly found by the group. Rachel Glascott from the Bay Group said it was "great for [volunteers] to be recognised for the work that they do".The Bay shared the Marsh Volunteer Award with Lincolnshire Wildlife Trust's beach clean volunteers.

In disaster-prone Vanuatu, photos show sea animals returning to battered reefs. Can recovery happen?
Beneath the turquoise waters of Vanuatu, amid a graveyard of broken coral, a moray eel peers from the branches of a staghorn colony. Nearby, the feathered arms of a yellow sea lily sway in the current and a turtle grazes on algae growing along the reef. These flickers of life hint at a slow but hopeful recovery. For the past decade, the South Pacific island nation's coral reefs have faced one punishing blow after another. Cyclone Pam in 2015 hit from a direction that left one reef particularly exposed.
