Etymology: Ctenopharynx: Greek, kteis, ktenos = comb + Greek, pharyngx = pharynx (Ref. 45335); pictus: From the Latin "pictus" = painted, coloured (Ref. 55925). More on author: Trewavas.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic; depth range ? - 78 m (Ref. 55925). Tropical; 24°C - 26°C (Ref. 2060); 9°S - 15°S
Africa: Endemic to Lake Malawi. Occurs in Monkey Bay, Nankumba, Otter Point, Domwe and Thumbi West Islands and the north end of Lake Malawi.

Morphology | Morphometrics
Diagnosis: high number of gill-rakers on lower outer arch (32-38); long head, 35.6-40.6% of standard length, and correlated with this a more posterior position of dorsal, pectoral and pelvic fins; long premaxillary pedicel, 33.0-38.4% head length (Ref. 55925).
Inhabits rocky areas with a deposit of fine sediment (Ref. 267, 55925), but also found on soft-bottom habitats (Ref. 55925). Feeds on small invertebrates, mainly benthic copepods (Ref. 267, 55925) obtained by sucking up the fine sediment and passing it over the gill-rakers (Ref. 267).

Phylogenetic diversity index (Ref. 82805
= 0.6250 [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
): 3.0 ±0.00 se; Based on food items.
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (14 of 100) .
