Shark attacks dropped in 2024. Here's where most bites occurred.
The latest iteration of the International Shark Attack File, a database run by the Florida Museum of Natural History and the University of Florida, showed that shark attacks decreased dramatically in 2024 and was far below the annual average.
"Unprovoked shark bites plummeted in 2024," reads the headline of the report, which characterized the year as "exceptionally calm" for shark bites.
Of 88 alleged shark-human interactions that researchers say they investigated last year, 71 bites were confirmed. The report segmented those incidents into unprovoked and provokes bites, of which there were 47 and 24, respectively. Seven of the attacks were fatal, including four unprovoked attacks, according to the research.
Those figures did not account for instances where sharks attacked a boat or bit a human who was already dead. Several additional incidents where a person's injuries could not be indisputably attributed to a shark, over another predatory marine creature, were categorized as "unconfirmed" in the report.
Confirmed attacks in 2024 dwarfed numbers reported in the previous year's International Shark Attack File, which recognized 91 global incidents, including 69 unprovoked bites and 22 provoked bites. Ten people died in shark attacks in 2023, with six killed in unprovoked attacks, researchers said at the time.
The number of attacks last year was "well below" the 10-year average, of about 70 unprovoked shark bites recorded annually, the new report notes. It also calls the four unprovoked attacks a "significant reduction" compared with previous years.
The International Shark Attack File considers attacks on a living human in the shark's natural habitat, who did not bother the animal prior to being bitten, "unprovoked." It considers attacks that occur after a human has initiated some sort of contact with the shark "provoked."
Divers suffering bites after trying to touch or otherwise harass sharks, attacks on spearfishermen, bites on people who attempted to feed sharks, and bites that happen while a shark is being unhooked or removed from a fishing net, are some examples of scenarios that would meet criteria for a "provoked" attack.
Unprovoked bites are of particular interest to the researchers studying shark attack patterns.
"We're interested in the natural patterns of shark behavior so that we can understand why people occasionally get bitten by these animals," said Gavin Naylor, the director of the Florida Program for Shark Research, in a statement. "Any cue or attribute that modifies an animal's natural behavior is something that, we as scientists, want to exclude."
Places with the most unprovoked shark attacks
Most of 2024's unprovoked shark attacks happened in the United States, which follows a longstanding pattern, the new report notes. Last year, there were 28 confirmed shark bites in U.S. waters, accounting for 60% of the worldwide total despite being lower than the 36 unprovoked incidents confirmed in 2023.
Half of U.S. attacks took place in Florida in 2024, which is also common for the state often known to experience the highest concentrations of shark bites of anywhere in the world. Like the national total, unprovoked shark bites were down in Florida, where the five-year average is 19 unprovoked attacks.
Australia trailed the U.S. total with nine unprovoked bites, a sizable decrease from the country's five-year average of 15. Egypt, the Maldives, Western Sahara, the Turks and Caicos Islands, French Polynesia, Mozambique, India, Thailand, Trinidad and Tobago, and Belize each reported one unprovoked shark attack.
The fatal attacks occurred in the U.S., Egypt, the Maldives and Western Sahara, with one death confirmed in each place, according to the Shark Attack File. Despite Florida's tally of unprovoked bites, the only U.S. death in a shark attack last year happened in Hawaii when surfer Tamayo Perry was killed off the island of Oahu. The species of shark involved in that attack is unknown, researchers said.

'Old people smell' is real, experts say — here's how to avoid it as you age
Many people have posted on social media about the so-called "old people smell," described as a faintly musty or greasy scent sometimes associated with older adults. This phenomenon is more science than stigma, experts say. "I think we all know this smell," Dr. Dan Wesson, professor at the University of Florida College of Medicine, told Fox News Digital. "Some describe it as dusty, like an old book. Others as oily or greasy. None of these, of course, are flattering descriptions, and that's why this isn't the kind of smell you want to label a person with," he noted. The skin is the largest organ in the body, so it makes sense that it will undergo significant changes as the body ages, according to Wesson. For most of our lives, body odor stems from sweat, bacteria and dead skin, which can be addressed with basic hygiene. But with aging, changes in skin composition and oil production make smells more complex, the expert noted. "Skin cells accumulate damage over time," he said — and those damaged cells can release compounds that contribute to odor. A key culprit is 2-nonenal, a compound that emerges from lipid oxidation, which is the process of fats in the cells breaking down due to imbalances in the body, studies show. This compound is unique to aging skin and has a greasy, cardboard-like odor. 2-nonenal is not easily washed off with regular hygiene practices, "by nature of its fatty composition," Wesson said. "This is why managing this body odor requires more complex solutions," he said. Wesson suggests taking a more holistic approach by eating antioxidant-rich foods like fruits and vegetables, staying hydrated and using antioxidant skincare. Some medications — including those for high cholesterol, ADHD or depression — could also impact the body's metabolism and how much it sweats, contributing to odor, according to Wesson. Hormones can also influence how people smell. Post-menopausal women often experience changes in skin and scent due to declining estrogen levels, studies show. "Hormone replacement therapy can ward off some changes that may alter body odor – though [HRT] is not without risks and should be discussed carefully with your doctor," Wesson said. Not all odor changes are normal, experts warn. "A sudden change in body odor can be a warning sign of an underlying health issue," Wesson warned. Diseases like cancer and dementia, for example, can alter body chemistry and scent. "If your loved ones report a sudden change, you should consult your doctor," Wesson advised. Some people may worry about how they smell even when others wouldn't notice. That concern could stem from parosmia, a distorted sense of smell, or olfactory hallucinations, where unpleasant smells are imagined. "People can perceive odors that aren't there at all," Wesson said. "It's important to consider whether it's a real odor or just a change in perception."

Conservation group celebrates astonishing milestone after removing over 20 tons of invasive snakes: 'We're moving in the right direction'
Thanks to a collaborative effort between the Conservancy of Southwest Florida and researchers at the University of Florida, over 20 tons of Burmese pythons have been removed from Southwest Florida. "We like it when a scout snake does not locate a female or there are fewer and of a smaller size class. That indicates that we're moving in the right direction, with the goal of local population suppression," said Conservancy biologist Ian Bartoszek, per the Naples Daily News. So, what's the deal with Burmese pythons, and why do they need to be removed? Unfortunately for Floridians, they are an aggressively invasive species and a severe problem in Florida's Everglades. The ecological impact is serious. Burmese pythons are known for being "generalist" predators, meaning they consume a wide variety of wildlife. In 2012, the USGS (United States Geological Survey) documented a 99.3% raccoon population decline, a 98.9% drop in opossums, and an 87.5% drop in bobcats, all while marsh rabbits, cottontail rabbits, and foxes all but disappeared entirely. The effect on native plants throughout the region is relatively unknown, though it's hard to imagine that drastic herbivore population declines won't impact native plants. What really makes Florida's Burmese python issue so complicated is the snake's hunting habits. They're hard for scientists and hunters to detect thanks to their camouflage and the difficulty of the Everglades terrain. It's so arduous that Florida has taken a containment approach over an elimination strategy, utilizing bounty hunters among other groups to gain some semblance of control. Things are not much easier when dealing with invasive plant species, either. Like the Burmese python, many of the over 755 invasive plant species in the U.S. grow rapidly, overtaking native species by robbing them of nutrients. Fortunately, personal lawn battles against invasive plants are a bit easier than the elusive python. Upgrading to a natural lawn draws in pollinators, who help shield our food supply as one of the most important aspects of nature's lifecycle. Should we be actively working to kill invasive species? Absolutely It depends on the species I don't know No — leave nature alone Click your choice to see results and speak your mind. Native lawns also boost the local ecosystem's harmony while reducing maintenance and saving gardeners and landscapers both time and money. While the campaign against Florida's Burmese python invasion is far from over, you can do your part by promoting a more balanced, natural ecosystem.
