Understanding Triggerfish and Their Cognitive Abilities

The video explores the intelligence of triggerfish, highlighting their problem-solving skills and social learning abilities. Researchers observed a titan triggerfish using clever tactics to hunt crabs, showcasing its cognitive abilities. Experiments by Hans Fricke demonstrated that triggerfish can solve problems and learn from each other. The video suggests that studying fish can provide insights into the evolution of intelligence. It concludes with a promotion for Brilliant's STEM courses.
