Cuttlefish ‘Talk’ With Their Arms, Study Reveals

ig. 1. Four distinct arm wave signs observed in adult Sepia officinalis (A–D) and juvenile Sepia bandensis (E–H): “Up” sign (A, E): The most frequently displayed gesture, characterized by upward extension of the first arm pair and outward extension of the fourth pair, while the second and third arm pairs are twisted at the midsection. “Side” sign (B, F): All arms are rolled to one side of the body, creating a lateral display. “Roll” sign (C, G): All arms are tucked and rolled beneath the head, altering its shape to highlight the eyes. “Crown” sign (D, H): Features a rapid “spitting” motion, with arms arranged in a crown-like formation.

Scientists have discovered that cuttlefish use distinct arm movements to communicate with each other, adding another dimension to these already remarkable marine creatures. Researchers from the École Normale Supérieure in Paris and the Italian Institute of Technology have identified specific arm gestures they’ve named “arm wave signs” that appear to serve as a communication system … Read more
