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 between cuttlefish. The study, published this month in bioRxiv, reveals that these underwater signals can be percei

Researchers just spotted cunning cuttlefish waving to one another with their tentacles, a previously unobserved behavior that pushes the boundaries of the creature’s intelligence. Cuttlefish—sometimes referred to as the “chameleons of the sea”—are renowned for their camouflage abilities. In other cephalopods, that color-changing capacity is also used for communication. And like other cephalopods, namely octopuses, cuttlefish are quite intelligent. The cuttlefish’s apparent waving behavior revea

Crafty cuttlefish employ several different camouflaging displays while hunting their prey, according to a new paper published in the journal Ecology, including mimicking benign ocean objects like a leaf or coral, or flashing dark stripes down their bodies. And individual cuttlefish seem to choose different preferred hunting displays for different environments. It's well-known that cuttlefish and several other cephalopods can rapidly shift the colors in their skin thanks to that skin's unique st
