We always hear that dolphins are smart but how smart are they actually? Lori Marino explains for Ted-Ed in this cute animation and it’s almost stunning how intelligent they are. Their encephalization quotient (brain size to body size) is second only to us dumb humans and goes into detail how they can pass down knowledge to their kids, understand language, empathize with other creatures and so forth.
It’s an interesting watch, for sure.
