Everything We Know About Sharks Is Wrong

For decades, we saw sharks as mindless monsters. We were wrong. 🦈 Sharks are older than trees, have survived all five mass extinctions, and sense the tiny electric fields given off by every living thing. Some form friendships, return to the same companions year after year, and may even learn from each other. Megalodon ruled the oceans for millions of years, and some Greenland sharks alive today may have been born before the United States existed. But the scariest part of the shark story isn’t what they do to us. It’s what we’re doing to them, and why losing sharks could unravel entire ocean ecosystems.
