Are megalodons still alive?
Even though online myths suggest that megalodons continue to inhabit the ocean depths, The particular type of shark has become extinct. states the Natural History Museum. The megalodon vanished by the conclusion of the Pliocene , which happened around 2.6 million years ago when the Earth started to cool down.
When ocean temperatures fell and food was hard to come by, approximately one-third of all large marine creatures died out. Since megalodons originated in tropical seas, the drop in temperature caused them to lose their habitat, according to the Natural History Museum.
Furthermore, it is thought that megalodons likely gave birth near the shore. However, when ice started forming at the poles and sea levels dropped, these habitats were ruined, as stated by the Natural History Museum.
There is a slim chance that megalodons still exist because such massive sharks would likely leave discernible bite marks on other large sea creatures. Additionally, their huge teeth should break under the pressure of the ocean floor. Furthermore, the present-day frigid depths of the ocean wouldn’t support warm-water species like these sharks.
