By explaining the chromatophore system of communication, students will gain an understanding of a particular type of cephalopod behavior. | | | The activity focuses on predator avoidance, mate recognition, and prey capture, so it is necessary to discuss these particular communications in your presentation. |

| | Re: Why are there no mammals with green skin or green hair? |
| | In mammalian skin and hair, there is only one type of chromatophore, the melanophore, which is instead called the melanocyte. | | | In fish, amphibians, and reptiles these chromatophores come in three flavors: melanophores full of melanins, which are brown/black; xanthophores full of pteridines and carotenoids, which are yellow/red; and iridophores with special "reflecting platelets" that can be silvery to iridescent or complement the other pigments to produce any number of other colors. | | | In most vertebrates, color, or pigmentation, is produced by special pigment cells called chromatophores (chromato means "color"; phore means "producer") that lie between the inner (dermis) and outer (epidermis) layers of skin. |
