Range and Identity
Catostomus insignis occurs in the Gila and Bill Williams systems of Arizona and New Mexico, with records in northern Sonora. The river-system description is more informative than a broad Southwestern label. Historical abundance statements should remain separate from recent survey evidence.
Habitat and Behavior
Adults inhabit rocky pools in creeks and small to medium rivers. Larger individuals occur in rocky riffles and runs at night. This time-related habitat observation means a daytime pool record and a nighttime riffle record can describe the same species without contradiction.
Food and Life History
The compiled maximum is eighty centimeters total length. An independent maximum weight and a detailed species-specific feeding or spawning account are not established in the available summary. A sucker’s mouth shape alone does not supply a complete diet.
Field Note
Include fish size and time of observation with the habitat record. Those details help explain the documented use of different rocky channel positions and prevent a daytime sample from defining all activity.
