| He subsequently investigated the endocrine regulation of chromatophores and eye pigments. |
| Previously, time-resolved fluorescence and transient absorption measurements have been performed using chromatophores from Rhodospirillum rubrum and Blastochloris viridis. |
| These cells, called chromatophores, are responsible for the ability of the cephalopods to change color and patterns accurately and rapidly in response to danger or emotion. |
| That triggers a signal from the brain to other cells, called chromatophores, which initiate the change in hue. |
| There are two lateral, discoid, brown chromatophores, each of which possesses a central amylum granule. |
| According to Anderson, the ability of chameleons to change color stems from special cells called chromatophores found in the upper layers of their skin. |
