The Hoosier cavefish (Amblyopsis hoosieri) is a subterranean species of blind fish from southern Indiana in the United States.

The choice of the name was also influenced by the fact that Prosanta Chakrabarty, the senior author of the paper that first described the species, was a fan of the Indiana Hoosiers college basketball team.

[1] The Hoosier cavefish is usually found in pools in slow-flowing cave streams, in water that ranges from more than 2 metres (6.5 ft) deep to as shallow as 10 centimetres (4 in).

[1] The species is threatened by a number of factors: sedimentation from agriculture, human encroachment on its habitat, and groundwater pollution by herbicides, pesticides, and fertilizer.

The species may also have been affected by over-collection of samples for scientific study during the late nineteenth and early twentieth centuries.

Due to these factors, the authors recommended that the species be classified as vulnerable on the IUCN Red List.
