The Zebra Mussels
Beware the zebra mussels!
They are horrid, they are dangerous, they are zebra mussels! Ever want to go on a boat cruise along the shore? Well, beware them then, if you ever want to again. Look on the car and the boat, for if you don't, you're in big trouble. I would be careful if I where you, you know.
They can eat through metal and your boat's anchor and motor. Ever heard of an animal that can hold onto a running motor? This is one of them, bet you thought it was impossible since not even the shark could. Anyway, they also damage humans, mostly on the legs and arms. As you can see, zebra mussels can be a pain, literally.
