Range and Identity
Noturus lachneri is recorded from the upper Saline River system and a small Ouachita tributary in central Arkansas. The Saline belongs to the wider regional drainage context, but records should retain their actual tributary. A general Ouachita label is less precise than the collection locality.
Habitat and Behavior
Adults occupy rocky pools, backwaters and runs in clear creeks and small rivers. The broader stream can be swift even when a fish occupies a locally sheltered patch. Both the overall channel setting and the immediate current around the fish are useful observations.
Size and Life-History Records
The compiled maximum is ten centimeters total length, with a common reference of 4.5 centimeters. These values describe length variation without establishing a maximum mass. The sparse summary does not support a detailed diet or a specific nesting schedule for all populations.
Field Note
Keep the local flow conditions with the rocky-bottom description. A backwater beside a swift creek is not the same habitat as an exposed riffle in its center.
