Megalodon Babies Grew by Eating Unhatched Eggs in Womb, Study Finds


New research released Sunday suggests Megalodon shark pups were born larger than most human adults, about 6.6 feet long, and feasted on unhatched embryos to reach such a large size.

(CN) As with most prehistoric sharks, little is known about their biology or behavior as the information scientists do have mainly comes from fossilized teeth, despite the animal leaving behind an otherwise rich fossil record. Those teeth are thought to have been able to exert an incredible 24,000 to 41,000 pounds-per-feet of bite force more than enough to crush bone. ....

Search teams at the site of the Indonesian Air crash continue to hunt for the black boxes of the aircraft, which investigators said broke apart after hitting the Java Sea, reports Bloomberg. The Boeing Co. 737-500 passenger jet carrying 62 people plunged more than 10,000 feet shortly after takeoff at 2:36 p.m. local time Saturday. Investigators are closing in on the flight recorders after detecting so-called pingers used to help locate the black boxes that capture sound in the cockpit and monitor the plane’s track and other flight data. ....

Megalodon, the largest species of shark ever to have existed in Earth s history, likely had a somewhat gruesome method for getting a head start in life.
According to new research, the pups of the Megalodon shark (
Otodus megalodon) are larger than most humans when they re born. This suggests that they hatched in the womb and were born live - and, like modern sharks that give birth to live young, grew by eating their unhatched siblings in utero. ....
