The Lake Victoria species pair Pundamilia pundamilia (A and B) and Pundamilia nyererei (C and D). Fish on the left (A and C) are from Python island, where the water is relatively turbid and hybridisation sometimes occurs. The more distinctly coloured fish on the right (B and D) are from Makobe island, where waters are clear and no hybridisation is observed.
