Misconceptions
-
Some skeptics argue that a few Megalodon sharks are still alive, but officially the Megalodon shark is extinct. One potential siting was in the early 20th century when David Stead, an Australian naturalist, reported giant white sharks terrorizing fishermen at Port Stephens. Scientists argue that this report is not valid because most of the eye witnesses were anonymous.
However, in 1938 a live Megalodon shark was captured which proves that a small population of Megalodon shark still survive, according to Eslamo-research.org. Less than 5 percent of the deep sea has been explored which makes this even more likely. Sharks live at depths as low as 12,000 feet below the surface.
Warning
-
Humans kill approximately 100 million sharks, rays and skates every year, according to the Florida Museum of Natural History. Fishing and killing too many sharks has a major effect on fish food chains and results in overpopulation of many fish species.

It wasn't a Megalodon that was found, it was a Coelacanth. No Megalodon sighting has been proven and they don't fossilize because they were made of cartilidge. The only thing scientists have to go off of is the teeth that were found of them.
