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
Freshwater; pelagic. Tropical; 7°N - 14°S
Africa: widely distributed in the lower and middle Congo River basin (Ref. 28136, 54749), including Sangha River and Ubangui River (Ref. 188), also 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)
soft rays: 19 - 24. Diagnosis: Body slender or moderate, depth about 22-29% of standard length; scutes beginning behind base of last pectoral fin ray; lower jaw strongly projecting, with strong canines at symphysis; one large canine tooth about halfway along normal pre-maxillary series, rarely a smaller one beside or a little behind it, curved and pointing backward; lower gill rakers 18-29, short, less than corresponding gill filaments and the anterior ones reduced to stumps in large adults; silver stripe along flank (Ref. 188, 54749). No prepelvic scutes present (Ref. 54749).
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).

Phylogenetic diversity index (Ref. 82805
= 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00933 (0.00449 - 0.01939), b=3.05 (2.88 - 3.22), 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) .
