The use of background matching vs. masquerade for camouflage in cuttlefish Sepia officinalis
Cuttlefish, Sepia officinalis, commonly use their visually-guided, rapid adaptive camouflage for multiple tactics to avoid detection or recognition by predators. Two common tactics are background matching and resembling an object (masquerade) in the immediate area. This laboratory study investigated whether cuttlefish preferentially camouflage themselves to resemble a three-dimensional (3D) obj...
متن کاملInteractive effects of size, contrast, intensity and configuration of background objects in evoking disruptive camouflage in cuttlefish
Disruptive body coloration is a primary camouflage tactic of cuttlefish. Because rapid changeable coloration of cephalopods is guided visually, we can present different visual backgrounds (e.g., computer-generated, two-dimensional prints) and video record the animal's response by describing and grading its body pattern. We showed previously that strength of cuttlefish disruptive patterning depe...
متن کاملDisruptive coloration elicited on controlled natural substrates in cuttlefish, Sepia officinalis.
Cephalopods are known for their ability to change camouflage body patterns in response to changes in the visual background. Recent research has used artificial substrates such as checkerboards to investigate some specific visual cues that elicit the various camouflaged patterns in cuttlefish. In this study, we took information from experiments on artificial substrates and assembled a natural ro...
متن کاملDisruptive coloration in cuttlefish: a visual perception mechanism that regulates ontogenetic adjustment of skin patterning.
Among the changeable camouflage patterns of cuttlefish, disruptive patterning is shown in response to certain features of light objects in the visual background. However, whether animals show disruptive patterns is dependent not only on object size but also on their body size. Here, we tested whether cuttlefish (Sepia officinalis) are able to match their disruptive body patterning with increasi...
متن کاملModular organization of dynamic camouflage body patterning in
Cephalopods have the most sophisticated dynamic skin coloration for rapidly camouflage in nature. Previous studies have suggested that the pair of optic lobes located bilaterally in their brain plays a key role in controlling the expansion of chromatophores for generating diverse body patterns. However, the functional organization of the optic lobes and their neural control of various body patt...
