First ever sighting of newborn great white reported
  + stars: | 2024-01-29 | by ( Katie Hunt | ) edition.cnn.com   time to read: +5 min
CNN —Drone footage shot off the coast of Southern California may have revealed the first ever glimpse of a newborn great white shark in the wild. Adult great white sharks are gray on top and white underneath. “I believe it was a newborn white shark shedding its embryonic layer.”The case for the baby great white sightingWhile in utero, embryonic sharks feed on unfertilized eggs for protein. If their assessment is correct, it’s the first time that a newborn great white shark has been observed in the wild. In addition, other researchers have suggested this location off the coast of central California is a birthing ground for great white sharks.

A Chicago-area zoo recently welcomed a new epaulette shark pup. AdvertisementAdvertisementA new shark pup is always cause for celebration at the Brookfield Zoo, but the birth of an epaulette shark has zookeepers especially excited due to its unusual conception. Epaulette sharks, which can reach up to 3 feet long at maturity, are easily identified by the large spots behind their pectoral fins. The birth of the pup in Brookfield marks the second known asexual birth of an epaulette shark in an accredited zoo or aquarium, per the release.

Florida's Volusia County is known as the "shark bite capital of the world." The area is a hot spot for shark attacks, especially on September afternoons, per the ISAF. Data from the Florida Museum's International Shark Attack File (ISAF), which describes itself as "the world's only scientifically documented, comprehensive database of all known shark attacks," shows that Florida is the global leader in shark attacks, with 259 from 2012 to 2021, well ahead of Australia in second place. But it is in Volusia County — which includes the renowned Daytona Beach and New Smyrna Beach — on Florida's east coast that has been dubbed the "shark bite capital of the world." The sharks that hunt the waters of Volusia County and are mostly involved in biting incidents include Blacktip, Bull, and Requiem sharks.

You may have heard that wearing bright colors may provoke shark attacks. Curiously, the tale goes, every man taken to his watery grave had one thing in common — they were all wearing orange pilot suits. This is a popular story in shark communities and is likely the origin of the myth that shark attacks may be caused by wearing bright colors, like yellow or orange. Sharks can't see color very wellThough Gruber's 1977 work confirmed sharks have sharp vision, it stopped short of drawing conclusions about color. Yellow and orange are the best colors to wear if you end up in a dangerous situation and want to be spotted by rescuers.

Unwanted interactions and shark sightings have made national headlines, and shark bites in popular tourist destinations have prompted temporary closures. Kathy Hochul deployed dozens of shark-monitoring drones to parts of the state after Long Island authorities repo rted five non-fatal shark bites over two days. In 1997, the US established the prohibited shark species group, which barred the possession, sale and purchase of several shark species, including white and sand tiger sharks. “If sharks … wanted to bite people, I think we’d probably have about between 10 and 20,000 shark bites a day,” said Naylor.

There were just 57 confirmed unprovoked shark attacks last year, out of a global population of 8 billion, five of which were fatal. However, some places around the world have much higher rates of shark attacks than others, with the numbers rising with the passing years. Let’s take a look at the locations worldwide with the highest rates of shark attacks between 2012 and 2021 and the reasons they’ve become hot spots. South Africa (29 bites)South Africa had 29 unprovoked shark bites between 2012 and 2021, of which six were fatal. South Carolina (45 bites)None of the 45 unprovoked attacks in South Carolina in the decade-long time frame were fatal.

But many species of these aquatic apex predators are now in danger of dying out forever. Of the thousand known species of sharks and rays (sharks’ closest living relatives), over a third of them are at risk of extinction. And since sharks are “indicators of ocean health,” as sharks go, so does the delicate balance of marine ecosystems. A 2021 report showed over the last 50 years, global shark and ray populations have fallen more than 70%. Listed as threatened under the Endangered Species Act, oceanic whitetip shark numbers in the Pacific Ocean have fallen an estimated 80 to 95% within the last 30 years, according to NOAA.

CNN —Shark patrols are ramping up off Long Island beaches after five people were bitten in two days by marine animals that are likely sharks, authorities say. Officials in Long Island’s eastern Suffolk County, where three of the attacks occurred, have increased beach patrols and are using drones to scour the water for potential threats, the Suffolk County Police Department said Tuesday. Though no sharks were seen by the girl or anyone nearby at the time of the incident, the bite was most likely from a shark, Gorman said. Also Tuesday, a 15-year-old boy was bitten on his foot by a shark while surfing off Fire Island’s Kismet Beach, Suffolk police said. Three more people were bitten on Tuesday, including a 47-year-old man swimming in chest-deep water off of Long Island’s Quogue Village Beach, local police said.

Juvenile white sharks grow up to become great white sharks, known for being dangerous to humans. Why juvenile white sharks swim near humans so oftenFrom the researchers' drone footage, it may look like juvenile white sharks like to hang around swimmers and surfers. The shallow water near the beaches "is actually the natural habitat the juvenile white sharks use. Why juvenile white sharks don't typically attack humansAlthough great white sharks are infamous for attacking humans, the actual number of attacks is low. However, it doesn't mean the risk of a bite from a juvenile great white is zero — it's just very low.

Shark attacks are more common in the US than in any other place in the world. But if you think shark attacks are only limited to remote and isolated islands, you'd be surprised to know that the US has seen more unprovoked shark attacks than any other country, by far, and many of these attacks happen near crowded beaches. Where the most shark attacks occur in the USSince the 16th century, 1,604 unprovoked shark attacks have been reported in the US, according to the International Shark Attack File. That's more than double the number of shark attacks in Australia, which holds the second-highest number of attacks at 691. "Shark attacks are rare and it is extremely rare for people to be eaten when they occur," Sorensen said.

A viral video on TikTok shows an alien-looking shark egg found on a California beach. The corkscrew-shaped egg came from a California horn shark, the TikTok user said. The video shows the "pliable" egg — and the tiny shark embryo moving inside. In the video, she shows the egg — which she says came from a California horn shark — is pliable and squishy but will harden over time. At one point in the video, the camera gets close enough to the egg casing to see the tiny, wriggling embryo inside.
Simon Nellist, 35, a diving instructor, was killed by a great white shark off Sydney in 2022. A report has classified Nellist's death as a "provoked incident." The International Shark Attack File (ISAF), a global database of all known shark attacks, has now classified Nellist's death as a "provoked incident," which refers to a situation in which a human unintentionally or intentionally initiates contact with a shark. "A big great white, that's a great white, oh no, that's insane, the person's still there." Barcroft Media/Getty ImagesThe Australian Shark Incident Database, unlike ISAF, has recorded Nellist's death as an "unprovoked incident."
