Regional Waters
Records include Pit River tributaries and waters of the Goose Lake region. These separate localities should remain visible in the range account. A general northern California label is not enough to assign every small sucker to Catostomus microps.
Appearance and Habitat
Fish use shallow muddy pools in cool creeks. The agency description notes a short head, small eyes and several darker body blotches. Breeding males develop orange or reddish coloration and tubercles, so a breeding photograph may look different from a nonbreeding fish.
Length Comparisons
The compiled maximum is 34 centimeters total length. Agency summaries also give smaller adult figures using standard length or an unspecified convention. Those values should retain their original endpoints rather than being treated as contradictory measurements on a single common scale.
Keep the Measurement Endpoint
Standard and total length differ at the tail. Preserve the convention when comparing agency descriptions with a measured Modoc Sucker.
