Dolphins have been seen using sponges, perhaps to protect their mouths from coral. And some bottlenose dolphins create rings of mud with their tails to trap fish.
"You don't need hands to create tools, you just need a clever mind," says Emory neuroscientist Lori Marino, an expert in dolphin neuroanatomy. Marino is speaking at the American Association for the Advancement of Science annual meeting on Sunday, Feb. Feb. 21, about how the high intelligence of dolphins calls for us to rethink how we treat them.
