Etymology: Campostoma: Greek, kampe = curved + Greek, stoma = mouth (Ref. 45335); anomalum: Campostoma=curved mouth and anomalum=extraordinary (Ref. 79012). More on author: Rafinesque.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic. Subtropical; 48°N - 26°N
North America: widespread across most of eastern and central U.S. in Atlantic, Great Lakes, Mississippi River, Hudson Bay (Red River) basins from New York and Ontario to North Dakota and Wyoming, and south to Georgia, Louisiana, and Texas (but absent from most of lower Ohio River basin}; Gulf Slope drainages of Texas. Also in Rio San Juan basin, Mexico.

Maturity: Lm ?  range ? - ? cm
Max length : 22.0 cm TL male/unsexed; (Ref. 5723); common length : 18.7 cm TL male/unsexed; (Ref. 12193)
Inhabits rocky riffles, runs, and pools of headwaters, creeks, and small to large rivers (Ref. 5723, 86798). Subadults and adults feed on detritus, filamentous algae, diatoms and occasionally on small aquatic insects; young on rotifers and microcrustacea (Ref. 10294). Reported maximum length is 17 cm TL (Ref. 86798).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00794 (0.00386 - 0.01635), b=3.12 (2.95 - 3.29), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 2.0 ±0.0 se; based on diet studies.
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (Fec=623).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (31 of 100) .
