(North American freshwater catfishes)
Etymology: Ictalurus: Greek, ichtys = fish + Greek, ailouros = cat (Ref. 45335); lupus: Ictalurus (Greek)=fish cat; lupus (Latin)=a wolf (Ref. 79012).
Environment / Climate / Range
Freshwater; demersal. Subtropical, preferred ?; 32°N - 26°N
North America: USA to Rio Grande drainage including Pecos River system in southeast New Mexico and Devils River in southern Texas; also in northeastern Mexico.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 48.0 cm TL male/unsexed; (Ref. 5723); 32.8 cm TL (female)
Inhabits sandy and rocky riffles, runs and pools of clear creeks and small rivers and also springs. Greatly resembles a small channel catfish, however, body lacks spots and the caudal fin is not deeply forked, the base of the anal fin is longer than the head length (see Ref. 3221).

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5010 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00832 (0.00379 - 0.01824), b=3.10 (2.91 - 3.29), based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.6 ±0.4 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Moderate to high vulnerability (51 of 100) .
