Meet the salmon louse (Lepeophtheirus salmonis), an aquatic parasite that poses a threat to the world’s salmon farms. Their prominent mouthparts latch onto a salmon’s scales and gills to feed on its blood. Along with salmon, these lice can also infect other salmonid species, such as trout and char. Parasites like these can cause irreversible damage to their host and pass along an array of diseases.
