Which colors are associated with yabbies inhabiting clear waters?
Answer
Black, blue-black, or a deep dark brown
The appearance of the common yabby is highly dynamic, changing its pigmentation based on environmental surroundings, particularly water clarity and the composition of the substrate. In habitats where the water is notably clear, *C. destructor* typically develops much darker pigmentation as a form of camouflage against the background. This coloration spectrum includes shades such as black, a deep blue-black, or a very dark brown, allowing the crayfish to blend effectively into shaded or darker bottoms characteristic of clearer aquatic systems.
