FFrontiers · 20.10.25↗Do animals fall for optical illusions? What fish and birds can teach us about perceptionDr Maria Santacà describes how not only how fish and birds perceive their worlds, but also how ecological pressures shape the evolution of perception.- 🐠 Some animals, like fish and birds, can be tricked by optical illusions just like humans. Scientists wanted to see if these animals see the world in the same funny way we do.
- 👀 The illusion used is called the Ebbinghaus illusion, where a circle looks bigger or smaller depending on the circles around it. It helps scientists learn how brains understand what they see.
- 🐟 Guppies, a type of small fish, were fooled by the illusion! They thought food surrounded by smaller circles was larger and went for it more often.
- 🕊️ Ring doves, on the other hand, were not easily tricked. Some saw the illusion, others didn't, showing that animals can see things differently.
- 🌍 This study shows that animals' eyes and brains evolved to fit their world, fish need to react fast in water, while birds focus on small seeds on the ground.
