Considering how nearly everything in the sea is eaten by some type of shark, does that mean that aside from whales, no sea creature is safe in the ocean? That's a great example of how dangerous sharks are. They are a literal force of nature, and they're the scourge of the seas.
Funny though, until reading this article, I never realized that the media exaggerates how threatening sharks can be, and I'm surprised that they only attack when provoked. However, though this may be true to an extent, it's always a good idea to be cautious regardless. After all, we (humans) may be at the top of our respective food chain, but sharks are still at the top of theirs, whether we go for a swim or not.
