41 - 18: Inside Animal Minds: Dogs & Super Senses

Humans rely on smell, sight, taste, touch and sound; other animals have super-powered versions of these senses, and a few have extra senses we don't have at all. From a dog that seems to use smell to tell time to a dolphin that can "see" with its ears, discover how animals use their senses in ways we humans can barely imagine. But it's not just the senses that are remarkable — it's the brains that process them. NOVA goes into the minds of animals to "see" the world in an entirely new way.
