What are these things? Icicles? Stalactites? Here’s a hint: chomp!
It’s been around a long time, but us humans have just gotten around to seeing it. Shark species are becoming extinct worldwide, and one expert estimates that of the species present ~50 years ago, 90% have become extinct. Since it is now clear there are species out there we’ve never encountered, there are probably even more species becoming extinct than what we are aware of. Ignorance is bliss? No, more like extinction.
