They never see the great white, only its fin. The sight strikes a sense of fear and awe into those who have witnessed it. Suddenly the seal disappears beneath the surface occasionally to be replaced by a circle of red blood bubbling up. The first indication of a great white’s presence is a circular blast of white water around a seal. Here is another interesting question, did the megalodons hunt their prey the same way that great whites hunt? The fishermen report sightings of great white often feeding on seal pups in mid-August when the pups have been weened. The megalodons simply could not adapt and compete with their smaller rivals for food, as reported by the BBC from a study led by Professor Tutken of Johannes Gutenberg University.ĭecorator crabs: The amazing spider crustaceans found in Hampton Beach tidepools The great white was smaller and quicker and could survive on less food. From this, the theory is that the megalodon and great white were competing for the same food in the same niche in the food chain and it looks like the great white out competed the megalodon contributing to their extinction.

Some have theorized that megalodons were cannibals. According to this study, it looks like both the great white and megalodons were eating about the same foods at the same time. They extrapolate those findings to determine how high up on the food chain an animal is or was. al, 2022, a group of scientists have developed a way to determine the nitrogen content of an animal’s diet by examining their teeth. It does not appear that the numbers of megalodons increased in warm water regimes or decreased in cold water.Ītlantic sturgeon: Endangered ‘prehistoric-looking’ fish spotted near Hampton HarborĪccording to a recent study by Kast, et. While some scientists originally believed that climate change caused the extinction of the megalodon this theory has been mostly disproved by the distribution of fossilized teeth.

This brings us around to extinction and the ability to adapt.

This allows them to swim and hunt in colder waters. So, while sharks are considered cold-blooded animals, these sharks have developed a way to increase their body temperature. This allows the sharks to heat their blood above the ambient water temperature.
