It's like a really awful B-movie come to life: Piranhas have been attacking beachgoers in northeast Brazil. AFP picks up a UOL Noticias report that about 100 people who braved the water at Piaui state's main beach last weekend had their toes or heels bitten, badly enough that they were treated at a local hospital. "Since they have no predators, piranhas have started attacking people on the beach," explains a local official. In an effort to sate the piranhas' hunger, officials are introducing tilapia into the waters. (More Brazil stories.)
