Amblyopsidae (Cavefishes)
Etymology: Amblyopsis: Greek, amblys = darkness + Greek, ops = shape (Ref. 45335); hoosieri: The specific name is in reference to this species being from the state of Indiana and also in reference to Indiana University, where biologist Carl H. Eigenmann was a Professor of Zoology and studied blind cave vertebrates, including populations of Amblyopsis hoosieri in Lawrence County. The name is derived from the proper noun Hoosier. The senior author of the manuscript is an avid fan of Indiana Hoosier basketball while the first author is an alumni of the
University of Michigan.
Eponymy: This sounds like an eponym but is in reality a sort of toponym. Hoosier is the nickname given to residents of the state of Indiana (where this cavefish occurs). (Ref. 128868), visit book page.

Raios dorsais (total) : 8 - 11; Raios anais : 8 - 10; Vértebras: 29 - 30. Differs from its only congener, Amblyopsis pelaea by having the following characters: body more plump, fleshy and rounded (vs. sculpted, thin) with Bibendum-like wrinkles along myomeres (vs. tight skin); pectoral fins rounder (vs. pointed); and mechansensory papillae on the body and caudal fin reduced in size and less elevated on the skin (vs. conspicuous) (Ref. 96073).
Inhabits mainly larger cave streams at or near the water table where it has been observed in slow flowing pools at depths as shallow as 0.1 m to > 2 m deep. Reported to feed on copepods, isopods, and amphipods but larger individuals prey upon small crayfish. Spawning probably takes place during high water levels from February through April. Females incubate eggs in their branchial cavities until hatching and continue to care for fry until yolk reserves are depleted 4-5 months later. Likely attains sexual maturity in 3-4 years (Ref. 96073).
