Snails the size of footballs are sludging their way across the world, killing crops and carrying meningitis along with them.
Known as giant east African snails, the invasive species has recently been discovered infiltrating Florida, nations in both Central and South America, and, most recently, Australia. The snails are kind of terrifying, seeing as how they can grow up to a foot long, can weigh in at over two pounds, and are capable of eating over 500 different species. Oh yes, they can also lay 1,200 eggs a year, and have few natural enemies in their new habitats. Also, they can transmit life-threatening meningitis to humans.
