Super Scents

Overview

Salmon smell their way to their spawning grounds, fulmars and petrels use tube noses to find food and pigeons navigate by smell. Impalas and wasps show alarm with scent and skunks use it to deter predators. Moths use scent to attract a mate and a salamander uses dracula teeth to inject an aphrodisiac. Smell governs the lives of termites and mole rats as well as 10,000 snakes in a pit in Manitoba. Even human odours may have hidden powers.
