Great white shark sightings spike as 11 seen this month off coast
A dramatic spike in the number of great white sharks has been detected in the waters off the US coast, according to global non-profit ocean research organisation OCEARCH. Between August 1 and August 10, 11 great white sharks have been "pinged" by tracking site OCEARCH off the eastern coast of the United States.
Among those to have appeared is the largest great white ever recorded by the organisation – Contender. Back in June, the apex predator was spotted heading straight towards a tourist beach.
And, more recently, the 13ft 9ins predator was 'Z-pinged' on August 2 and August 9 – meaning it spent some time on the ocean's surface. Other giant predators spotted this month include 13ft 3ins Breton and 13ft 4ins Bob.
The numbers are a sharp increase on previous months – with five white sharks pinged in July and just three in June. But Avery McAlhany, a Content Specialist at the organisation, has shared there's a very simple reason for the uptick in sightings.
She explained that OCEARCH, partnering with the Tancock Islands Marine Field Station in Atlantic Canada, have recently tagged, sampled and released seven new white sharks in the region.
Avery said: 'These sharks have been pinging frequently, which is common when tags are fresh and free from biofouling—the natural buildup of marine life on tags over time that can reduce signal clarity.'
Avery added that, in recent years, the team had identified a new trend in the sharks' migration patterns. She continued: 'The majority of white sharks in the western North Atlantic migrate north to Atlantic Canada or New England during the summer months, drawn by cooler waters and abundant food sources like fish and seals.'
Despite their fearsome reputation, great whites are only rarely responsible for fatal attacks on humans, often trying one 'sample bite' before swimming off to find something more to their taste.
Although stories of their poor eyesight tends to be exaggerated, great whites don't have good colour vision and cannot make out fine details as well we we can. They often mistake surfers and swimmers for their preferred prey, seals.
Around 90% of swimmers who are attacked are likely to live to tell the tale, according to figures from the California Department of Fish and Wildlife. That said, the ocean's apex predator has immensely powerful jaws, meaning that even one bite can cause catastrophic injuries.
There are some key pointers to avoid an encounter with these monsters of the deep. Circling birds, splashing water, a dead whale, large groups of seals and dolphins are all clues that a shark could be nearby.
Because great whites are really looking for seals, it's a good idea not to look like one. Plain, dark-coloured wetsuits can contribute to misidentification. Consider a brightly-coloured, patterned wetsuit instead.
Poor light can also cause cases of mistaken identity – avoid swimming very early in the morning or at dusk. Swimming alone is also inadvisable. If you are bitten by a shark, it's important to get out of the water as soon as possible and having a buddy nearby can make all the difference.
Even a small cut can attract sharks from a good distance away, so never swim if you have an open wound. Experts are divided over whether sharks can be attracted to acted when women are menstruating, but it's better to be safe than sorry. If you're on your period, maybe you're better off just sunbathing.
Dr. Harley Newton, chief scientist and veterinarian for OCEARCH, from Jacksonville, Florida, has dedicated her career to studying shark behaviour and educating the public about these often misunderstood predators - including Contender.
She has revealed the surprising thing you should avoid wearing when swimming in the ocean - and what do to if you do come face to face with a predator.
Dr Newton's advice includes avoiding dawn and dusk swims, staying close to shore, always swimming with a buddy, and to avoid wearing shiny objects such as jewellery.
She added that you should always try to maintain visual contact if you spot a shark, backing away slowly while facing it.
While shark attacks are rare, she stresses that you should always try to remain aware of the ocean's dangers.

Horror as pigs discovered with bright blue SKIN after being ‘exposed to pesticides' – with fears other animals infected
SWARMS of pigs have been found with neon blue skin after ingesting life-threatening pesticides. Officials warned other animals may also be contaminated including geese, deer and bears as hunters have been urged not to consume meat from any infected prey. 2 The electric blue-skinned hogs were first reported in Monterey County, California in March when trapper, Dan Burton, discovered several wild pigs with blue fat and muscle. He told LA Times: "It's wild. I'm not talking about a little blue. I'm talking about neon blue, blueberry blue.' The feral swine are thought to have ingested the rat poison from dyed bait or feeding off other infected species. As omnivores, they eat anything from grass to other bits of animal matter. The toxic chemical contains an anticoagulant Rodenticide Diphacinone which prevents blood clotting and causes internal bleeding. It's often dyed so it can be identified as poison. Dan said his company found the infected animals when he was hired to trap and kill wild pigs that were disrupting farmers' fields. But, while many of the pigs were found contaminated, not all possessed the gruesome cobalt flesh, The California Department of Fish and Wildlife said. This depends on how much of the pesticides they have consumed, it added. More than one feeding is needed to "receive a toxic dose" but humans or animals who consume even small amounts of the chemical will start feeling its effect, according to a 2023 study. Legionnaire's disease outbreak kills at least two and sickens dozens more after spreading at alarming rate across NYC This includes signs of lethargy - a state of tiredness, sluggishness, and lack of energy, often accompanied by a decreased level of consciousness. An study in 2018 by the University of Nebraska also found that the rat poison was present in over eight per cent of the wild pigs and 83 per cent of bears. News of the poisoned pigs comes as a woman was left with a life-threatening knee infection after being attacked by own rooster. The 26-year-old, who kept birds at her home in Switzerland, initially thought nothing of the small graze on her right knee left by the angry bird. She immediately cleaned and disinfected the wound before getting on with her day. But by the following morning, her knee had swelled up, turned red and become so painful she was forced to rush to hospital. Just a few months earlier, the unlucky woman had been treated in hospital with antibiotics after a cat bite. On inspection, doctors at Canton Hospital Basel-Land in Liestal, Switzerland, spotted a tiny lesion just above her inner knee. Writing in the BMC Infectious Diseases, the medics said the mark looked superficial at first. They would later discover the rooster's beak had punctured deep into the joint, causing serious internal damage.

Warnings issued in California over wild pigs found with blue meat
Californian authorities have issued warnings after wild pigs with 'bright blue' flesh were reported again, indicating they have been poisoned. The California Department of Fish and Wildlife received reports of this bizarre occurrence in March, confirming the phenomenon is a sign of poisoning. The blue coloration is attributed to exposure to the anticoagulant rodenticide Diphacinone, a poison that prevents blood from clotting. Wild pigs can ingest the poison by eating bait, which often contains dye, or by consuming other animals that have ingested the substance. Hunters are advised that game meat, including wild pig, may be contaminated, with previous incidents and studies confirming rodenticide residue in wild animals.
