Fish Eyes: More than Meets the Eye

Add to List
Go to Activity


In this data collection and analysis activity, learners evaluate fish physiology and ecology using vision research data from Dr. Kerstin Fritsches at the University of Queensland in Brisbane, Australia. Learners plot data on graphs to investigate relationships between a species' maximum diving depth and its lens diameter, speed of vision, and cone types. Learners explore how vision adaptations help the fishes as well as how visible light in water and color vision help fishes.
