* Larger Sharks: Larger shark species like Great Whites, Tiger Sharks, and Bull Sharks will sometimes prey on smaller sharks. This is especially true if the smaller shark is sick, injured, or a young pup.
* Orcas (Killer Whales): Orcas are known to hunt and kill large sharks, including Great Whites. Their intelligence and hunting strategies allow them to target and take down even the largest and most powerful sharks.
* Other Large Predators: In some cases, sharks can be preyed upon by large marine mammals like seals, sea lions, and even polar bears. However, this is not a common occurrence.
* Human Impact: Humans are a significant threat to sharks through overfishing, habitat destruction, and bycatch. This can disrupt the natural food chain and leave sharks vulnerable to other predators.
It's important to remember that while sharks are at the top of the food chain, they are still vulnerable to other predators and environmental factors.
