Etymology: Odaxothrissa: Greek, odax, = with the teeth + Greek, thrissa, -es = shad (Ref. 45335);  losera: The species name losera is a common name of the species at its type locality (Ref. 54749).  More on author: Boulenger.

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

Freshwater; pelagic.   Tropical; 7°N - 14°S

Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Africa: widely distributed in the lower and middle Congo River basin (Ref. 28136, 54749), including Sangha River and Ubangui River (Ref. 188), but also in Lualaba River (Ref. 188) and Upper Lualaba River (Ref. 45434). Perhaps also in rivers of Angola (Ref. 188).

Size / Weight / Age

Maturity: Lm ?  range ? - ? cm
Max length : 13.0 cm SL male/unsexed; (Ref. 188)

Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 15-18; Anal spines: 0; Anal soft rays: 19 - 24. Diagnosis: Body slender or moderate, its depth about 22-29% of standard length; 10-14 pre-pelvic and 7-10 post-pelvic scutes, no pre-pectoral scutes, first scute beginning slightly before or behind base of last pectoral fin ray and identical as following scutes without ascending arms; lower jaw strongly projecting, with strong canine teeth at symphysis; pre-maxilla with one large backward-pointing canine tooth on each side, about halfway along normal pre-maxillary series, rarely 1-2 smaller ones beside or a little behind it; lower gill rakers 18-29, shorter than corresponding gill filaments and the anterior ones reduced to stumps in large adults; anal fin with 19-24 rays; silver stripe along flank (Ref. 188, 54749). It resembles Pellonula vorax, which lacks canine teeth in the upper jaw and has one or more pre-pectoral scutes (Ref. 188).

Biology     Glossary (e.g. epibenthic)

Found in rivers and streams (Ref. 188), also lakes (Ref. 41580). A small predator, feeding on shrimps, mayfly nymphs and little fish (Ref. 41580, 54749).

Estimates based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.6250   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00912 (0.00433 - 0.01920), b=3.04 (2.87 - 3.21), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.1   ±0.3 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.).
Vulnerability (Ref. 59153):  Low vulnerability (14 of 100) .
Price category (Ref. 80766):   Low.
