Colour Change

Those unfamiliar with the underwater world may ne surprised by the extent to which fish change colour. Some change their colours and patterns, quite dramatically as they mature. Others change colour to camouflage themselves, some do it as a means of communication. Octopus & cuttlefish not only change colour, they also change texture.
