Figure

Fig. 2. Experimental set-up. (A) Experimental tank with a dichromic patternuniform 18% grey to uniform black then back to uniform 18% greybottom
Fig. 3. Body reflectance of cuttlefish as they cross the experimental tank.(A) When crossing a control grey tank, none of the eight cuttlefish drasticallychanged its reflectance
Fig. 4. A cuttlefish matching its background as it swims from a black to agrey background
Fig. 5. A representative reflectance map of the 10mantle segments during a change in background.Each mantle segment changed reflectance almostsimultaneously, with no evidence of a gradual change.
