Light and the Behavior of Organisms examines how living beings orient themselves to light, showing why some creatures move toward shaded areas and others away from light.
This edition surveys a wide range of life, from simple organisms to more complex animals, to explain the mechanisms behind light‑guided movement.
Readers will see how researchers test orientation, the difference between responses to changes in light versus constant illumination, and how localized light changes can steer behavior. The discussion draws connections across groups like planaria, Euglena, stentor, echinoderms, mollusks, arthropods, and vertebrates to reveal a unifying picture of light‑driven motion.
- How organisms respond to varying light intensities and directions
- The role of localized stimulation in guiding movement
- Several comparative examples across major animal groups
- The evolution and interpretation of theories on orientation in biology
Ideal for readers curious about animal behavior, sensory biology, and the science behind how light shapes movement.
