Cuttlefish swim by undulating the fins on each side of their bodies and/or using their funnel to jet away in any direction. In this picture, one can see the left fin gently undulating. https://images.squarespace-cdn.com/content/v1/577aa2aabe65944fd9c7cd50/1472667813643-4DUKGIPID0BZN1XK2VI9/image-asset.jpeg Cephalopod bioacoustics Beside changing color, cuttlefish can also change the texture of their skin by raising little skin papillae. This cuttlefish raised two papillae above its eye and many more over its body to give its skin a rough and granular texture. https://images.squarespace-cdn.com/content/v1/577aa2aabe65944fd9c7cd50/1472656034412-GSGO8PHTZF3I6QGIFI2A/image-asset.jpeg Cephalopod bioacoustics Figure 7 from Samson et al., 2014: the experimental set-up.

Below the chromatophore layer, iridophores reflect light and produce iridescent colors, as can be seen on the underside of this cuttlefish. https://images.squarespace-cdn.com/content/v1/577aa2aabe65944fd9c7cd50/1472667854799-KAAIZ6MLSJ88SEW0F14Z/ceph_banner.jpg Cephalopod bioacoustics http://www.juliaesamson.com/news-archives daily 0.75 2018-10-29
