Megalodon, the massive prehistoric shark species, is believed to have gone extinct due to the rise of its smaller relative, the great white shark. Scientists have theorized that the emergence of great white sharks, which were more agile and faster hunters, resulted in a decline in the population of Megalodons. The competition for food and resources ultimately led to the extinction of Megalodon and the survival of the great white sharks, who continue to thrive in oceans today.
