Cuttlefish are known to use more than color-changing and posture to communicate — new research suggests they wave their tentacles to send signals. Scientists at École Normale Supérieure observed four distinct wave patterns and found cuttlefish respond both visually and through water vibrations. With plans to use AI and robotics to decode these gestures, researchers hope to unlock a deeper understanding of cephalopod communication. This could be a major step forward in interpreting animal behavior and intelligence in marine environments.
