When does a chameleon change colour?
A chameleon changes colour when it senses danger. Being a member of the lizard family, the chameleon can change colour to match its background or to become almost unrecognizable.
A part from its response to danger, the chameleon can change colour according to the light and temperature too. This mechanism is controlled from the nervous system and involves the dispersion of colour pigments in the creature’s skin.
