Piscicolidae
Piscicolidae is a family of leeches, commonly known as fish leeches, that are exclusively parasitic on fish. These ectoparasites are found in freshwater and saltwater environments across the globe. They are characterized by their elongated, segmented bodies and a unique adaptation for attaching to their hosts: a sucker at the anterior end (head) and another at the posterior end (tail). This allows them to firmly grasp their host’s body, facilitating blood feeding.
