Learn about the cognitive abilities of dolphins in this video excerpt from NOVA scienceNOW: "How Smart Are Animals?" Correspondent Doug Hamilton meets with researcher Stan Kuczaj and dolphin trainer Teri Bolton to explore the intelligence of dolphins. In one experiment, dolphins display the ability to think and plan ahead to get a fish out of a box more efficiently. In another, two dolphins demonstrate their ability to plan and communicate with each other when they are signaled to create a new trick together. Dolphins vocalize with clicks and whistles, but scientists do not yet understand their language.
