What sea animal kills sharks?

There isn't one specific sea animal that "kills" sharks in the way we might think of a predator-prey relationship. However, there are several animals that can pose a threat to sharks, depending on the species of both the shark and the predator:

* Larger Sharks: Larger sharks, like Great Whites, Tiger Sharks, and Bull Sharks, can prey on smaller shark species.

* Orcas: Orcas (killer whales) are known to hunt and kill sharks, especially Great Whites. They're highly intelligent and coordinated hunters, using teamwork to overcome even large sharks.

* Other Marine Mammals: Some other marine mammals, like dolphins and large seals, can also attack and kill sharks, particularly if the shark is injured or young.

* Fish: While not as common, some large fish, like swordfish and marlin, can injure or kill sharks with their powerful beaks.

It's important to remember that sharks are apex predators in many ecosystems, and while they face threats from other animals, they are generally at the top of the food chain.
