In addition to the well-known extraordinary changes in visual appearance they can generate at level of their mantle, cuttle-fish produce various body configurations combining chromatic, postural, and locomotion patterns, both for camouflaging communication. We introduce a previously undescribed communication display two cuttlefish species: Sepia officinalis bandensis. The four “arm wave signs” are stereotyped arm movements consisting long-lasting, expressive, repeated sequences undulations arms, which be combined expressed following specific patterns. Using non-invasive behavioral experiments, we tested hypothesis that represent multimodal displays. To assess role cues, recorded videos animals signing played them back individual participants. When seeing movies, waved display. Most importantly, were more likely when movie was upright (original) configuration as opposed flipped upside-down, similar manner humans perceive faces other socially relevant visually striking display, signs mechanical waves water, prompting us explore possibility may also perceived via mechanoreception. playback experiments those adopted vision, obtained preliminary evidence support this hypothesis, indicating signals involving vision Our new result on with opens up novel possibilities understanding vibration-mediated through lateral line and/or statocysts cephalopod species an example convergent evolution vertebrates.
