Larger Sharks:
* Larger sharks: Larger sharks like great white sharks, tiger sharks, and bull sharks will occasionally prey on smaller shark species.
* Orcas (Killer Whales): Orcas are known to hunt sharks, especially great whites, by targeting their livers.
Other Animals:
* Other Marine Mammals: Some large marine mammals like sperm whales and pilot whales may occasionally eat sharks.
* Large Fish: Very large fish like marlin and swordfish could potentially prey on smaller shark species.
Other Factors:
* Disease and parasites: Sharks can be affected by diseases and parasites, which can weaken them and make them vulnerable to other predators.
* Human activity: Humans are a major threat to sharks through overfishing, habitat destruction, and accidental bycatch.
Important Note: Sharks are generally at the top of their food chains, and their predators are typically larger, more powerful, and more specialized in hunting them.
