Range and Identity
Older accounts treated cavefish north and south of the Ohio River under one species name. The description of Amblyopsis hoosieri changed that interpretation. A locality in an older Northern Cavefish account therefore needs checking before it is included in the modern range of Amblyopsis spelaea.
Habitat and Behavior
Underground streams and pools provide the characteristic setting. Bottom conditions can include rock, mud, sand and silt. Darkness and groundwater connections are central features, but a named cave alone does not describe the full connected habitat available beneath the surrounding landscape.
Size and Life-History Records
The lack of ordinary visible eyes and strong pigmentation reflects its cave-associated form. Detailed reproductive claims and upper measurements from older broad accounts are not transferred without checking their population identity. This avoids turning a historical combined-species description into a precise modern maximum.
Field Note
Attach the collection date and exact cave system to an identification. Those details help interpret records made before the neighboring species was recognized.
