These geckos possess the significant ability to dramatically change in colour intensity based on the presence or absence of light on or around them. The gecko appears bright green in light, but if kept in a dark place, even for a short period of time, its appearance darkens to an extremely dark green that could easily be mistaken for black when viewed in light. If a light is then shone on the gecko, a visual change seems to occur separately in each scale-like protuberance and gradually the entire gecko changes to a bright green in the light over a period of less than 3 minutes. The tail however changes slightly slower. During the change the gecko appears as a mottled bright and dark green simultaneously. See included images taken in Praslin, Seychelles.
