Trichomycterus rivulatus is a species of freshwater ray-finned fish belonging to the familyTrichomycteridae, the pencil and parasitic catfishes.[2] This catfish is found in high-altitude Andean streams and lakes (including Junin, Poopó and Titicaca) in southern Peru, western Bolivia and northern Chile.[3] It is the largest species in the genus Trichomycterus and grows to a maximum length of 37.4 centimetres (14.7 in)TL.[3] The species is regularly caught as a food fish. However, because of pollution, studies have revealed levels of metals in T. rivulatus of Lake Titicaca that exceed the internationally recommended safety thresholds for human consumption.[4]
