This vivid Blue Koura is seen underwater, clutching an NZ $10 note with a Whio Duck drawn on it, not really so strange as they do share the same habitat. Koura occupy streams, lakes, ponds and swamps. They are an important part of freshwater ecosystems, as cleansers of the system by scavenging waste on the streambed, and filtering sediment; and as a food source for eels, shags and blue duck.
"Cobalt Blue may seem a risky colour for a koura, which are typically brown. But surprisingly, blue genetic variants of these freshwater crayfish are not uncommon in one or two of the deeper lakes around New Zealand. Blue koura survive because the colour spectrum of light shifts as it passes down through the water, and at a certain depth there is no visual difference in colour between a blue crayfish and a brown one—and therefore no difference in predation either"....from this website (
