Diffusion of “Smell” and “Taste”: Chemical Communication
- 701 Downloads
The natural world is filled with a vast variety of “invisible,” “inaudible” smells upon which animals depend for their lives through chemical communication. For the behavior of many mammal species, in particular carnivora and nocturnal animals, the role of the olfactory sense is more important than that of the auditory sense. Animals living in underground burrows, deep-sea fish, and many species of insects make use of smell. In the deep sea, with its low turbulence and perpetual darkness, scent may perhaps be even more important for aquatic animals than for terrestrial organisms (Hamner and Hamner, 1977).
