Classification / Names Common names | Synonyms | Catalog of Fishes(genus, species) | ITIS | CoL | WoRMS | Cloffa

Teleostei (teleosts) > Siluriformes (Catfishes) > Ictaluridae (North American freshwater catfishes)
Etymology: Noturus: Greek, noton = back + Greek, oura = tail; refred to the position of the tail over the back (Ref. 45335);  crypticus: Name from the Greek stem 'kryptos', meaning hidden or secret, referring to this species' secretive habits, and for having kept its identity in secret for so long..

Environment: milieu / climate zone / depth range / distribution range Ecology

Freshwater; benthopelagic. Tropical

Short description Morphology | Morphometrics

Dorsal soft rays (total): 6; Anal soft rays: 15 - 17. Diagnosis: Distinguished from other members of the Noturus elegans species group by having: modally 16 anal rays (vs. 18 in Noturus fasciatus); modally 8 pelvic rays (vs. 9); 2-10 medium-large sized melanophores on the cheek (vs. large melanophores absent on cheek); adipose fin band extending only to base or half-way up fin (vs. extending half-way up to edge of fin in fasciatus); adipose and caudal fins distinctly joined at their juncture (vs. weakly connected in fasciatus); three evenly spaced pale and dark bands in caudal fin (vs. caudal fin bands usually two and unevenly spaced); robust body shape, with body width at pectoral fin origin 23% or more of SL and greater than anal fin base length (vs. slender body shape, with body width at pectoral fin origin 22% or less of SL and less than anal fin base length). There is an absence of shared alleles for eight allozyme loci (mAAT-A, sACOHA, GPI-B, LDH-B, sMDHP-A, Pep-b, Pep-D, and PGM-A) distinguishes crypticus and fasciatus, which also differ by 5% Cytb sequence divergence. Similarly, both share no alleles at eight allozyme loci (mAAT-A, sAATA-A, sACOH-A, FUM-A, GPI-A, GPI-b, LDH-B, sMDHP-A, and Pep-D) and are 6.3% divergent for Cytb (Ref. 56218).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.3   ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
