In this Sunday, Sept. 22, 2013 photo, released by the community news blog, Voz de Areia Branca, a tractor is used to remove a dolphin carcass from Upanema beach in Areia Branca, Brazil. Around 30 large dolphins beached themselves in northeastern Brazil over the weekend, and news reports said Monday that at least seven of them had died. The dolphins, known as false killer whales, ran aground early Sunday on the shallow sands of Upanema beach.
