Megalodon, the world̵
The study, published in the scientific journal Historical Biology, suggests that these massive sharks were born more than 6 feet in length, thanks to eating undeveloped siblings while still developing during pregnancy.
“The gigantism of O. megalodon is due to the evolution of regional endotherm, probably together with the derived live-bearing reproductive regime, including intrauterine cannibalism in the form of oophagia,” the researchers wrote. “Yet how exactly O. megalodon has evolved throughout his life remains largely in the realm of speculation.”
MEGALODON FOSSILS DISCOVERED WORLDWIDE
Intrauterine cannibalism is not uncommon among sharks. In November 2019, a species of shark found in Kansas also depicted intrauterine “cannibalistic behavior.”
In September, a separate group of researchers determined the true body size of the megalodon, including its huge fossil-based fins. The 52.5-foot-long megalodon probably had a 15.3-foot-long head, a 5.3-foot-high dorsal fin and a 12.6-foot-tall tail, the researchers found.
Scientists led by Kenshu Shimada have used a number of methods to come up with their findings, including multiple X-ray CT scans to reconstruct fossils and get an idea of how big a megalodon is at birth.
Shimada and other experts also found that the massive shark grew 6.3 inches a year for the first 50 years of its life. Experts estimate that the lifespan of megalodons is about 88 years and can reach 100 years.
“As one of the largest carnivores that ever existed on Earth, the evolution and extinction of O. megalodon must have contributed to the shaping of today’s marine ecosystem,” the researchers added. “Therefore, deciphering such growth parameters of O. megalodon is crucial to understanding the role that large carnivores play in the context of ecology and evolution.”
The megalodon may have disappeared due to the overtaking and overtaking of its smaller, more agile cousin, the big white.

Other theories suggest that the megalodon was killed by an exploding star about 2.6 million years ago.
Another theory that attracted a lot of attention in the last memory is that the megalodon was simply not able to regulate its body temperature. The colder ocean temperatures during the Pliocene era caused the preferred food, whales, to adapt until the megalodon failed,
During the disappearance of the Pleistocene, many animals weighing more than 80 kilograms disappeared, according to the Illinois State Museum. With a length of about 50 feet and a weight approaching 120,000 pounds, megalodons would be the main candidate to be affected by the space explosion.
