During the reign of megalodons, the world was warmer and the oceans were teeming with life. Megalodons were the largest sharks to have ever lived, with estimates suggesting they could grow up to 20 meters in length. They were apex predators, feeding on large prey species, including other predators. Megalodons were highly mobile and inhabited various oceans, possibly undertaking transoceanic migrations. However, their extinction around 3.5 million years ago was influenced by several factors. Global cooling and a drop in sea levels led to the drying up of coastal habitats and the loss of resource-rich marine sites. This, combined with the decline in prey species and competition with other predators such as the great white shark, contributed to their demise. The extinction of megalodons had global consequences, disrupting nutrient transport between ecosystems and releasing other animals from their immense predatory pressure. The decline of apex predators like megalodons can destabilize entire ecosystems. Conservation efforts today aim to protect sharks from a similar fate caused by human activities.
