Range and Identity
Notropis oxyrhynchus is tied to the Brazos River system in Texas. The basin-level account includes the lower portions of large tributaries, but should not imply that every small headwater or every historical site is occupied today. Dated locality records remain important.
Habitat and Behavior
Adults favor sand and gravel runs in medium to large rivers. They occur less often in sandy or muddy pools. This contrast describes a preference within the river channel, rather than treating all water in the Brazos drainage as equivalent habitat.
Food and Life History
The upper reference is 9.5 centimeters standard length. Diet records include aquatic and terrestrial invertebrates alongside detritus and plant material. The fish is described as a batch spawner, meaning reproduction is not represented by one universal egg release or a fixed brood count.
Field Note
Keep the measurement convention visible and record the river reach. The source’s common-size figure uses total length, so it is not directly equivalent to the standard-length upper value.
