Argulus fish parasite, stained specimen, darkfield photomicrograph
Argulus is a crustacean, of the class Branchiura. These parasites are found on the skin and gills of fish. Argulus feed by inserting a pre-oral stylet into the skin that injects digestive enzymes, which break-down proteins, allowing the parasite to suck out body fluids. The spines, suckers, and hooks argulus use for attachment cause further irritation. Argulus infestation can cause focal, red lesions on the body of the fish.
