Etymology: fusiforme: The species name fusiforme is derived from the Latin fusus, spindle, and forma, shape; a noun in apposition (Ref. 85854).

Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt) : 15 - 16; Rückenflossenweichstrahlen (insgesamt) : 11 - 12; Afterflossenstacheln: 3; Afterflossenweichstrahlen: 8 - 10. Diagnosis: Coptodon fusiforme is distinguished from all Tilapia and Coptodon species by the combination of a slender fusiform body, an acute mouth, a pitch black breeding colouration and the 'tilapia spot' being extended to a longitudinal stripe in juveniles (Ref. 85854). It further differs from other Tilapia senso lato except Coelotilapia joka, Congolapia bilineata and all members of Coptodon in tricuspid pharyngeal teeth in the posterior two rows of lower pharyngeal jaw; it differs from Coelotilapia joka in more gill rakers on first ceratobranchial, 10-11 vs. 6-8; and from Congolapia bilineata in a caudal fin not densely scaled (Ref. 85854).

Deepwater specimens primarily feed on planktonic organisms in the open water column; inshore specimens pick on small particles from substrate and feed on allochtonous matter from water surface (Ref. 85854). The 'little-black' form breeds in all depth zones; the 'large-black' form breeds preferentially in log-holes of dead wood in the shallow region above 1 m (Ref. 85854).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 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): 2.7 ±0.1 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
