... chromatophores in colour change. Our Review concludes that the physiological costs result from either one or a combination of the processes of (i) production, (ii) translocation and (iii) maintenance of pigments within the colour-containing cells (chromatophores). In addition, both types of colour change...

...Tomás Horacio Delgadin; Diana Carolina Castañeda-Cortés; Clara Sacks; Andrés Breccia; Juan Ignacio Fernandino; Paula Gabriela Vissio ABSTRACT Morphological background adaptation is both an endocrine and a nervous response, involving changes in the amount of chromatophores and pigment concentration...

... Chromatophores Animals were tested separately. After being placed at one end of the experimental tank each animal was left to settle for at least 5 min. We then waited until two conditions were met: (1) The animal remained motionless on one side of the tank; (2) The body colour became uniform...

... mainly undertake various non-image-forming tasks. They form specialised photosensory systems that measure the quality and quantity of light and enable appropriate behavioural and physiological responses. Chromatophores are dermal non-visual photoreceptors directly exposed to light and they not only...

... or chromatophores extending centrally from dorsal and ventral reservoirs are filled with pigment during the light-adapted state but empty in the dark-adapted state. The locus of each transmission measurement was noted on both detailed drawings and photographs of the corneal pigmentation pattern. For each cornea...

...F. DUBAS; P.R. BOYLE Innervation of chromatophore muscles of the octopus Eledone cirrhosa was investigated by stimulating nerve bundles in the skin with a suction electrode and monitoring chromatophore movements with a photo-cell or a video camera. Attention was focused on the organization...
