Jellyfish: Surprising Learning Abilities and Deadly Venom

Scientists have discovered that jellyfish, despite lacking centralized brains, possess advanced learning abilities similar to humans and other complex organisms. In a study, Caribbean box jellyfish were trained to spot and dodge obstacles, challenging the traditional belief that advanced learning requires a centralized brain. These seemingly simple creatures have a complex visual system with 24 eyes, allowing them to navigate through murky waters and avoid underwater obstacles. The study sheds light on the evolutionary roots of learning and memory and highlights the potential for advanced learning in even the simplest nervous systems.
