Megalodon Sharks - Are They Still Alive?

February 14, 2024

Some people think that megalodon sharks are still alive hiding at the bottom of the Mariana Trench. Due to a lot of fake documentaries and odd youtube videos as well as the recent movie "Meg" many people believe that the giant megalodons are still alive. The answer is a resounding no!

Megalodons were giant, apex predators that ruled the prehistoric oceans. These monsters had massive jaws that were 10 feet (3 meters) wide and teeth up to 7 inches (17.8 centimeters). They were warmblooded and could live in both cold and warm waters, but they preferred warmer waters where they hunted for larger marine animals like other sharks, whales and sea lions.

However, at the end of the Pliocene, a major ecological event occurred. North and South America collided, shutting down the tropical currents that connect the Atlantic and Pacific Oceans. This drastically changed ocean temperatures, currents and nutrient flows. These changes also impacted the coastal nurseries Megalodons used to raise their young. Whale diversity also shrunk as some species went extinct and others adapted to cooler, polar waters where megalodons couldn't follow.

These factors, along with the fact that apex predators are particularly vulnerable to any environmental disruption, led to the extinction of Megalodon and all of the other large marine animals of the time. The evidence of their extinction is clear in the fossil record. Fossils of whales, sharks and squid are common in the well studied marine Pleistocene formations, but fossils of megalodons are nowhere to be found.
