A macro underwater photograph of a freshwater amphipod (Gammarus lacustris), commonly known as a scud. The specimen is visibly infected with a parasitic Acanthocephalan worm, evident as an orange spot along the dorsal abdomen. The typical olive coloration of the scud has faded to a pale bluish-green, a known symptom of parasitic infection. Education | Nature | Science | Horizontal | Outdoors
