In this picture you can see the surface topography of Dascyllus albisella, reconstructed from the six greyscale images in the previous image. This image captures the lateral line, visible at the top of the image as a row of scales connected by a canal. Heights on this surface are shown as colours: the warmer the colours (oranges and reds), the higher the heights. The height range of this surface is just over 200 microns – the highest parts of the surface are over 200 microns higher than the lowest .
