As human beings, if there's one thing we're really, really good at, it's driving species to extinction. You're probably doing it right now, without even trying. So it's paradoxical that there are some species out there that we just can't exterminate, and not for want of trying. These creatures breed out of control and march steadily forth, taking human territory miles at a time. So while you're sitting there, calmly reading things on the Internet ...
8Zebra Mussels Are Choking the Rivers
What happens when a creature can produce one million eggs a year? This.
They all have names, and at least 40,000 are called Dave.
Those are zebra mussels. They invaded the USA by hitching rides in the ballast water of Russian ships, and once they hit the rivers in the U.S., they spread rapidly, dominating the Great Lakes. So what's the big deal? It's not like they bite or anything. Well, zebra mussels only do one thing, but it turns out that they're really, really good at it: They stick.
Sailors call them "Congressmen of the Sea."
All they need is a hard surface that stays still for 20 seconds, and they'll superglue themselves right on that shit, covering boats, anchors, motors, lobsters, turtles and even other mussels. Those who can't grab hold of anything wind up washing up by the tons on beaches.
This isn't just inconvenient for turtles who suddenly find themselves weighed down in a sticky mussel flash mob -- the cost to us is catastrophic. In 1989, for example, a city in Michigan lost its water supply for three days because the mussels had crammed themselves into the pipe, cementing it shut.
"We're going to need all the Drano."
Since then, millions of dollars have been spent each year attempting to control the legions of mussels, but we can only slow them down. They can't be eradicated with chemicals without contaminating the water supply, and they multiply too quickly to remove by hand.
In short, these mussels are kicking our asses, which is pretty good for an animal that doesn't know how to move or do anything.
It's like a sit-in protest against the whole of humanity.
