Janelia researchers devised a novel system using predator robots to study learning in larval zebrafish, revealing that these young fish can learn quickly in natural scenarios. Traditional lab methods posed limitations; thus, scientists simulated real-world experiences to uncover the fish's rapid learning abilities. Their findings indicated that just five days after their birth, zebrafish could effectively distinguish between predator and non-predator robots, showcasing unexpected intelligence in these developing creatures. This breakthrough enhances understanding of brain-controlled behavior in young vertebrates and the cognitive capabilities of larvae.
It was an open question: how smart larval zebrafish were in terms of being able to learn rapidly.
Instead, the team decided to simulate a real-life experience: being chased by something that does not initially look like a predator.
