From Jaws to Sharknado, there’s one species that keeps its reputation of being one of the most feared and deadly predators in the ocean - sharks. Sharks have remained one of the longest living species in recorded history, living through five mass extinctions. Even the first shark recorded came 200 million years before the first dinosaur recorded. Yet, today, the dinosaurs have gone extinct and sharks are still around. And so, this evokes a question: What makes sharks so successful in staying away from extinction? In my research, I have come to a conclusion. This being that this species has survived for so long because of where they live, their attitudes and behaviors as well as how they’re designed and developed. Each paragraph will go deeper into exactly what about sharks has kept them successful.
As stated above, one of the largest factors of their long string of success is

This has impacted their survival in a larger manner than their environment has. For example: Sharks aren’t picky eaters. In the food chain, if a predator loses its prey due to extinction or endangerment, it’s likely that the predator will go extinct as well from lack of food. However, since sharks will eat nearly anything that moves, this has kept them from dying from starvation. These cartilaginous beasts’ meal is only variable by size. Smaller sharks will eat smaller prey (such as plankton, shrimps and small fishes). But bigger sharks will eat bigger prey (such as bigger fishes, seals and possibly dolphins depending on which shark we’re talking about. Even when they’re children, they have a natural instinct of being a carnivore. When born, the baby sharks swim right away - no parenting required! They have a natural instinct of being carnivores. This also helped the shark species survive as they don’t have to look after their kids, saving them lots of time and energy that they can put into other
