Can a whale shark eat thresher shark?

It's highly unlikely that a whale shark would eat a thresher shark. Here's why:

* Diet: Whale sharks are filter feeders. They primarily eat plankton, krill, and small fish. Thresher sharks, on the other hand, are active predators that hunt larger fish and squid.

* Size: While whale sharks can grow to be extremely large (up to 40 feet), they are not known to actively hunt and kill other large sharks. Thresher sharks, while large, are much smaller than whale sharks, and it's unlikely a whale shark would even notice one.

* Behavior: Whale sharks are gentle giants and are not known to be aggressive towards other marine animals. Thresher sharks are more agile and use their long tails to stun prey, but they don't typically attack animals as large as whale sharks.

Conclusion: While it's theoretically possible for a whale shark to encounter a thresher shark, it's highly improbable that the whale shark would consider it prey or attempt to eat it.
