An oil spill from a capsized cargo ship in the Indian Ocean is washing ashore on the pristine beaches of Thailand's most famous resort island, a lawmaker told AFP Friday.
The Panama-flagged Sealloyd Arc sank off Phuket on February 7 while sailing for Chattogram in Bangladesh, Thai authorities said, spilling around 1,700 liters of oil.
The coagulated residue has begun washing up on the island's Ya Nui Beach, as well as a smattering of smaller islands in Phuket province, local lawmaker Chalermpong Saengdee told AFP.
The oil has tainted Koh Hey's Banana Beach -- a popular destination for island-hopping tourists seeking turquoise clear waters -- and is expected to keep spreading, he said.
"It's very worrying because the incident happened two weeks ago, but the situation is not improving and it poses a threat to marine life and coastal reefs," he said.
"We are also concerned it could affect Thailand's tourism and economy."
The ship lies at a depth of about 60 meters (197 feet), making it difficult for divers to contain the leak, Chalermpong said.
Footage on public broadcaster Thai PBS showed locals combing beaches with rakes and buckets to collect globs of the oil.
While the Thai Navy has been using dispersants to treat the spillage, Chalermpong has called for government funding to salvage the wreck.
Thailand suffered 130 oil spills affecting more than 23 provinces between 2017 and 2021, according to the Department of Marine and Coastal Resources.
Environmental organizations warn oil spills cause severe and long-lasting damage to ecosystems -- coating wildlife, contaminating food sources and releasing toxic chemicals.

The winner of this year's Fat Bear Week has been crowned after a nail-biting final -- and it's the son of a former champion.
Backpack, a 20-year-old male beloved by rangers in Alaska for his quiet determination, edged out female fellow finalist Dancing Queen in the annual ursine eating competition at Katmai National Park.
More than 2.3 million people voted in the week-long competition that sees bears unwittingly jostle in a series of head-to-head contests to decide which one of them has most impressively piled on the pounds ahead of hibernation.
Viewers watch a livestream of the enormous animals as they scoop salmon from the Brooks River, while visitors to a dedicated website can browse biographies of some of the top contenders, including before-and-after pictures showing how much weight the bears have gained over a summer of feasting.
Backpack's victory -- by a razor-thin margin of just 5,000 votes out of 200,000 cast for the final alone -- continues something of a family tradition: his mother Holly is a previous winner.
The animal, known officially by the more prosaic name Bear 89, was nicknamed Backpack by rangers who noted his habit of climbing on his mother's back when she swam across the river, AFP reported.
He previously suffered a leg injury that left him with a limp and has apparently adapted his lifestyle, preferring to spend his time lazing on a rock, rather than fighting with fellow bears.
"Unlike many large adult male bears, Backpack hasn't shown much aggression toward his competitors," his contestant profile says.
Sarah Bruce, a Katmai park ranger, told Alaska Public Media that Backpack now weighs around 1,200 pounds (544 kilograms) and is a clear fan favorite.
"He's one of the bears that we've been able to watch on the live cams since the live cams were put in in 2012," she said.
The bears of Katmai spend summer and early autumn gorging themselves on salmon as they look to bulk up ahead of a long winter of hibernation.
For five months, the creatures will not eat or drink, slowing all bodily functions as they shelter away from the harsh Alaskan weather.
While the increasingly popular annual competition is largely for fun, organizers say it is helpful in raising awareness of brown bears and their Alaskan habitats, as well as the risks they face from human activity.
Butterfly Wing Patterns May Trick Predators with Motion Illusionshttps://english.aawsat.com/varieties/5324615-butterfly-wing-patterns-may-trick-predators-motion-illusions

When a bird lunges at a butterfly in mid-flight, it may see something that is not there — the insect's wings flashing beneath may not be moving where they appear to be moving. By the time the predator realizes the illusion, the butterfly already may have escaped.
Researchers studying this natural defense have found that contrasting wing patterns can work together with wing movements to create misleading motion signals, making it harder for predators to judge a butterfly's speed and direction during flight.
"The patterns on butterfly wings combine with their wingbeats to create optical illusions, making it look like the butterfly is moving in a different direction to its actual course," said Jolyon Troscianko, a professor at the University of Exeter in England and a leader of the study published in the journal Nature. "This is likely enough to save a butterfly from the split-second moment when a bird would try to catch it."
The idea that stripes and other bold markings can create "motion dazzle" has long been proposed by scientists. But experiments involving animals including zebras, snakes and lizards have produced mixed evidence, and many studies did not account for the movements of wings or limbs.

"Butterfly wings are flexible surfaces that clap together and fling apart, and also pivot forwards and backwards in a figure-of-eight as they fly. This movement means that a stripe across the forewings can be visibly and slowly moving down on the down-stroke," Reuters quoted Troscianko as saying.
"But on the up-stroke, this stripe is rapidly folded away and twisted in line with upwards flight direction. Together these make the downwards motion of the butterfly much more visible than its upwards motion, even though it is flying up," Troscianko added.
To investigate the idea, the researchers combined high-speed filming of real butterflies, computer modelling, simulated evolution and touchscreen experiments.
"Stripes are particularly good at interfering with the circuits that detect motion," Troscianko said. "The barber pole illusion is a good example — stripes moving sideways can look like they're moving up or down instead."
The patterns also appear to increase uncertainty about a butterfly's position during an attack.
"This increased 'confusion' effect would be almost impossible to overcome without evolving a fundamentally different visual system," Troscianko said, suggesting it may have been pivotal to the success of the butterflies as a group.
Not all butterflies appear to use this strategy, however.
"The least motion-confusing butterflies are typically brown or red," Troscianko said, suggesting that some species may rely more on camouflage or on warning colors that may signal to predators that the insect is toxic, poisonous or has a bad taste.
To test whether the effects could influence attacks, the researchers recruited 100 human volunteers and carried out 3,000 virtual butterfly-catching experiments. Participants watched videos and attempted to catch butterflies by tapping a screen. Butterflies that were predicted to produce stronger visual confusion caused people to aim farther behind them.
"Predation experiments with live birds and butterflies would have been ideal in many ways, but likely impossible and unethical in practice," Troscianko said.

Because the neural circuits involved in motion vision are quite fundamental in vertebrates, Troscianko said, the researchers hope the findings can translate between different species.
Butterflies face multiple predators, and motion confusion may not fool them all equally.
"For now, we've only looked at bird vision," Troscianko said. "In principle, similar effects could happen in predatory insects like dragonflies and robber flies. However, they have much faster vision than birds, so the illusions might not work for them. Indeed, dragonflies and robber flies do successfully hunt butterflies quite often."
Beyond biology, the team's motion-vision tools could have practical applications, from improving how movement is displayed in flight or combat simulators to developing patterning that protects personnel, vehicles, drones or robots in motion when being targeted visually.
"I'm most excited to explore how useful our models could be for improving road safety and reducing discomfort and stress in the built environment, where flashing, moving and striped objects can cause harm or danger," Troscianko said.
Shark Stranded in South Korean Canal Draws 600,000 Visitors as Rescue Bid Failshttps://english.aawsat.com/varieties/5324601-shark-stranded-south-korean-canal-draws-600000-visitors-rescue-bid-fails
Shark Stranded in South Korean Canal Draws 600,000 Visitors as Rescue Bid Fails

A shark stranded in a canal in the South Korean port of Busan has become the country's latest wildlife sensation, with the city saying about 600,000 people have flocked to see it over the past two weeks.
The 3.5-meter shark was first spotted in a narrow waterway in North Port on September 18, according to Reuters.
As the days passed without the shark finding its way back to the ocean, authorities launched a rescue operation on Tuesday to guide it out, but the effort failed.
The Coast Guard and other agencies deployed vessels to spray jets of water behind the shark to gently propel it toward the open ocean, but it swam away from the streams, according to videos published by Yonhap News Television.
Officials now plan to use a net to try to guide the shark out of the canal on Friday, the Chosun Daily reported.
The shark, reported to be a bronze whaler, has become something of a celebrity in South Korea and has been dubbed “Bukangi,” a nickname derived from “Buk Hang,” the Korean name for Busan’s North Port, and the Korean suffix “-i.”
During the four-day Chuseok holiday last weekend, about 480,000 people visited the waterfront park where the shark was stranded, compared with the park's usual daily average of around 2,000 visitors on weekends, according to a Busan city statement and media reports.
On Tuesday, Busan declared the shark an honorary public relations ambassador for the city after a poll on the city’s official Instagram account received 91% approval from about 8,000 participants.
Other animal escapades have gripped South Korea in the past.
Earlier this year, a wolf that escaped from its enclosure at a South Korean zoo spawned a cryptocurrency meme coin and even prompted a message of concern from the country's president.
