Etymology: Otopharynx: Greek, ous = hear + Greek, pharyngx = pharynx (Ref. 45335).
Environment / Climate / Range
Freshwater; demersal. Tropical; 9°S - 17°S
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 24.5 cm TL male/unsexed; (Ref. 4991)
Africa: Occurs in Lake Malawi and the upper Shire River.
Common at 10 m depth and prefers the area where non-breeding individuals congregate into schools over the sandy part of the biotope. Feeds on phytoplankton or takes its food from the somewhat muddy layer on the substrate (Ref. 5595).

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01445 (0.00589 - 0.03548), b=3.03 (2.82 - 3.24), based on LWR estimates for this Subfamily-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 2.0 ±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 (25 of 100) .
