Studies have shown that Baby Megadon is a 6-foot-long uterus cannibal



Scanned a subset of about hundreds of vertebrae (grapefruits of some sizes) and found that the shark had died at the age of 46. The researchers estimate that the shark’s life expectancy is about 88 to 100 years, which means that their specimens are about Dr. Shimada said: “middle-aged.” They also calculated the earliest age of the shark and found that the shark was born. It may be longer than six and a half feet.

Cooper, who did not participate in the study, said: “This is really a big baby.”

Dr. Shimada said that to reach such an astonishing scale, newly born Megs might snack on each other while in the womb. Most sharks hatch from eggs in their mothers and are then born in a young form. But the cubs of some species are not friendly to roommates: after hatching, they start to eat their unhatched siblings at will, which helps them become fatter before they are born.

“It is this kind of high-calorie, high-nutrition diet that can help these embryos become larger and faster,” said Alison Bronson, who studies fish evolution at Humboldt State University in Arcata, California. .

With such a heavy weight, the mini buckets may be ready to compete with potential predators, or at least dwarf many of them. The strong appetite, coupled with the blood descent, may have helped them swallow a lot of prey, further aggravating the teenage terrorist activities.

Mr. Cooper said that this study provides important data on a poorly understood animal. But he pointed out that some of the calculations it uses are based on data collected in the 1990s, when researchers relied more on great white sharks to estimate various aspects of the anatomical structure of the giant tooth don. He said that comparing two animals that are too close may lead to “some specific body sizes being underestimated.”

Dr. Bronson said that it is also difficult to know the representativeness of this single Megalodon in his species. She said: “There are many kinds of fish.” “Even fish of the same age and species can grow at a completely different rate and reach different sizes.”

Researchers did not know that giant mothers would have difficulty carrying and giving birth to a six-foot-tall cub. Cooper said: “But although the baby is really big, so are adults.” At maximum size, some megalodons may have crossed the length of a bowling lane, which can even accommodate an embryo the size of a basketball player. Enough space.
