Piscicolidae [Piscicolidae]

Description

Piscicolidae is a family of leeches primarily found in marine and brackish environments, although some species are known to inhabit freshwater. These leeches are ectoparasites of fish, attaching to the host's skin or gills to feed on blood. Piscicolid leeches are elongated and can vary in color, often matching their host to avoid detection. They are distinguished by their large anterior sucker, used for attachment to hosts, and a smaller posterior sucker. The family includes genera such as Piscicola, which contains species known for their impact on commercial aquaculture by causing anemia and transmitting diseases to fish.
