ريخت شناسي | ريخت ستجي بوسيله انداره گيري
خارهاي باله پشتي (کل): 0; شعاع نرم باله پشتي (کل): 7; خارهاي باله مخرجي 0; شعاع نرم باله مخرجي: 7 - 10. Diagnosis: Amphilius ruziziensis is diagnosed from A. pedunculus, A. frieli, and A. crassus by its more slender caudal peduncle, caudal peduncle depth 8.6-9.5% of standard length vs. 9.7-12.3%, and from A. jacksonii, A. pedunculus, A. crassus, and A. lujani by its narrower interorbital width, 23.4-25.1% of head length vs. 26.7-35.8% (Ref. 103388). It is further diagnosed from A. frieli, A. crassus, and A. lujani by its more slender body, body depth at anus 11.1-12.9% of standard length vs. 13.5-17.4% (Ref. 103388). Amphilius ruziziensis is further diagnosed from A. frieli by having fewer branchiostegal rays, 6-7 vs. 8-9, fewer total gill rakers on the first gill arch, 6-8, rarely 5 or 9 vs. 10-11, rarely 9 or 12, and a longer caudal peduncle, caydal peduncle length 18.7-20.3% of standard length vs. 14.4-16.4%; it is further diagnosed from A. crassus by a longer caudal peduncle, caudal peduncle length 18.7-20.3% of standard length vs. 13.3-15.5%, and shorter dorsal-fin insertion to adipose-fin insertion length, 38.2-41.5% of standard length vs. 42.2-44.6%; it is further diagnosed from A. jacksonii by its deeper caudal peduncle, caudal peduncle depth 8.6-9.5% of standard length vs. 4.8-7.9% (Ref. 103388).

50 = 0.5000 [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 ±0.3 se; based on size and trophs of closest relatives
جهندگی (Ref.
