But now chimps, crows -- even dolphins -- have been spotted using them." Describes chimpanzees "clean[ing] themselves with wads of leaves, or us[ing] them like a sponge to soak up water for drinking," green herons using bait while fishing, dolphins carrying sponges to protect their beaks, and more.
