Cuttlefish Communicate Using Elaborate Arm Movements and Water Vibrations
2025-05-07
Scientists have discovered that cuttlefish use distinct arm movements to communicate, employing a multi-sensory system involving both visual cues and water vibrations. Researchers identified four distinct arm gestures, combined with skin color changes, that appear to convey different meanings. Remarkably, cuttlefish seem to perceive these signals differently depending on their orientation, similar to how humans perceive faces. Furthermore, experiments revealed that cuttlefish can detect these signals through water movement, likely utilizing their lateral line and statocysts. This dual-channel communication system adds a new dimension to our understanding of cephalopod intelligence and animal communication.
