No single person killed the biggest shark (Megalodon); instead, the apex predator likely died out due to a combination of climate change reducing its prey (whales moving to colder waters), competition from other predators like orcas and great whites, and the loss of its warm-water nursery grounds, with some theories even suggesting a supernova's radiation played a role.
Why did megalodon go extinct? We know that megalodon had become extinct by the end of the Pliocene, 2.6 million years ago, when the planet entered a phase of global cooling.
In fact, Megalodon might not even have been the largest predator in the ocean at the time it was alive - the recently discovered Leviathan whale (Livyatan melvillei) was potentially larger than Megalodon and occupied the same territorial waters.
No, 25-foot great white sharks likely don't exist; while historical reports claimed massive sizes (up to 37 ft), current scientific consensus confirms the largest reliably measured great whites are around 20 feet (6 meters), with most adults being smaller, though females are generally larger than males, with the fictional "Jaws" shark being significantly larger than any verified real shark.
Mature megalodons likely did not have any predators, but newly birthed and juvenile individuals may have been vulnerable to other large predatory sharks, such as great hammerhead sharks (Sphyrna mokarran), whose ranges and nurseries are thought to have overlapped with those of megalodon from the end of the Miocene and ...
The Great White Shark is considered the "#1 deadliest" due to having the most recorded unprovoked attacks and fatalities, followed closely by the Tiger Shark and Bull Shark, which are also highly dangerous due to their presence in coastal areas and opportunistic feeding habits. While Great Whites are powerful apex predators, Bull Sharks are known for their aggression and ability to live in both saltwater and freshwater, making encounters more likely.
At a length of more than 50 feet (15 metres) and a mass of nearly 50 tons (tonnes), Megalodon was both larger and heavier than Tyrannosaurus rex.
Although Deep Blue was tagged with a short-term tracking device in 2014 by the Woods Hole Oceanographic Institution, the tracker became dislodged. Scientists can only speculate about where and when she will turn up next. As of 2024, Deep Blue was still alive, but there have been no confirmed sightings in 2025.
If a shark charges, fight back
“That happens nine times out of 10.” If that does not work, and a shark tries to bite a swimmer—or even has a limb in its mouth—Naylor says the best course of action is to poke the shark hard in the eyes.
An adult great white shark has just one predator: the orca. Until recently, orcas have only been observed regularly preying on these sharks in South Africa, where they usually prefer to hunt larger adults, which provide more food once caught.
Despite what you might see online and in the media – no, megalodon no longer exists, except in a museum. We know this for a number of reasons. Firstly, because sharks lose so many teeth in their lifetime, we'd soon find a recent megalodon tooth that could be reliably dated to the present day.
The blue whale (Balaenoptera musculus) is a marine mammal and a baleen whale. Reaching a maximum confirmed length of 29.9–30.5 m (98–100 ft) and weighing up to 190–200 t (190–200 long tons; 210–220 short tons), it is the largest animal known to have ever existed.
Greenland sharks are large, mysterious creatures that roam the chilly waters of the north Atlantic and Arctic oceans. These elusive animals are considered the longest-living vertebrates on the planet, and they can survive to be roughly 400 years old.
Weaknessess: Plagued by lactic acid after long physical activity, probably avoids the conflicts (As modern sharks), can't live on the land, probably cannot swim in fresh bodies of water.
The fact modern orcas hadn't even evolved yet when megalodon went extinct and that ancestral orcas were bottlenose dolphin-sized small-prey specialist that were physically incapable of competing with even a newborn megalodon is something mammal/orca fanboys tend to ignore entirely.
Nope. Even if we could, it'd be a baaad idea. Bringing back animals that went extinct based on environmental factors that they weren't equipped for/they evolved into something better is really bad. Wastes resources, and they'd die out again anyway, or cause disaster for our modern ecosystem.
Shark repellent refers to methods or devices designed to keep sharks away from an area, using magnetic fields, electric pulses, or strong smells (like dead shark extract) to disrupt their senses, with Sharkbanz (magnets) and electric deterrents (like RPELA) being popular personal options, while in business, "shark repellent" also means tactics companies use to fend off hostile takeovers, like golden parachutes. Both marine and business applications aim to deter unwanted approaches, though effectiveness varies and is often debated.
The Greenland shark is the animal known to live up to 400 years, making it the longest-living vertebrate, with some individuals estimated to be even older, while the Ocean Quahog clam (Ming) lived over 500 years, holding the record for the longest-lived animal overall.
The 134.2-metre Lürssen superyacht Deep Blue has been spotted on sea trials following her launch in June 2025. Construction on the secretive superyacht began in 2021, with details surrounding the project kept tightly under wraps.
The Tyrannosaurus Rex: King of the Dinosaurs.
They could statically hold up the weight a car (or elephant) at those tooth positions with masses of 3.5-6.5 tonnes, and likely lift (accelerate upwards) minimum masses of 2.3-4.3 tonnes with modest effort.
The biggest great white sharks can reach up to 20 feet long, but most are smaller. The average female is 15-16 feet long, while males reach 11-13 feet.
