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

Teleostei (teleosts) > Cichliformes (Cichlids, convict blennies) > Cichlidae (Cichlids) > Pseudocrenilabrinae
Etymology: Ctenopharynx: Greek, kteis, ktenos = comb + Greek, pharyngx = pharynx (Ref. 45335);  intermedius: From the Latin "intermedius" = intermediate, probably referring to the fact that, according to Günther (1864) "this species connects Chromis and Hemichromis" (Ref. 55925).

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 14 - 17; Dorsal soft rays (total): 10 - 13; Anal spines: 3; Anal soft rays: 9 - 11. Diagnosis: high number of gill-rakers on lower part of outer gill arch (36-39); short head, 32.3-35.8% of standard length; relatively anterior implantation of dorsal, pectoral and pelvic fins; short premaxillary pedicel, 30.4-33.6% head length (Ref. 55925).

Biology     Glossary (e.g. epibenthic)

Found in sediment-rich areas (Ref. 5595) of the rocky habitat (Ref. 5595, 55925), the intermediate habitat, over sand, and in the open water (Ref. 5595). Feeds on plankton (Ref. 5595).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.6250   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01230 (0.00600 - 0.02521), b=2.93 (2.76 - 3.10), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  3.4   ±0.45 se; based on food items.
Generation time: 1.9 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (K=0.57).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (24 of 100).
Price category (Ref. 80766):   Unknown.
