"Jellyfish: Unveiling the Surprising Learning Abilities of Brainless Creatures"
A new study published in Current Biology reveals that box jellyfish, known for their deadly venom and lack of brains, are capable of learning and changing their behavior. Researchers trained the jellyfish to avoid obstacles in a low-light environment, demonstrating that they can learn through their nervous system without a brain. This challenges the belief that associative learning requires a brain. The jellyfish learned to navigate by combining mechanical and visual stimuli, suggesting that learning may be universal for organisms with nervous systems.
