Short description Morfología | Morfometría

Espinas dorsales (total): 0; Radios blandos dorsales (total): 22-25; Espinas anales 0; Radios blandos anales: 28 - 31; Vértebra: 44. Diagnosis: Marcusenius krameri can be distinguished from its congeners by following characters: middle body depth 21.9-28.1% of standard length; distance from dorsal fin origin to end of caudal peduncle 39.9-41.7% of standard length; distance from anal fin origin to end of caudal peduncle 42.8-44.9% of standard length; dorsal fin length 15.5-20.0% of standard length; anal fin length 23.2-25.5% of standard length; depth of caudal peduncle 26.0-40.6% of its length; scales around caudal peduncle 16; total vertebrae 44; anterior gill rakers (5-6)+(5); total anterior gill rakers 10-11; posterior gill rakers (8)+(9); total posterior gill rakers 17; dorsal fin rays 22-25; anal fin rays 28-31; scales along lateral line 69-72; conical teeth on upper/lower jaws 4-6 (Ref. 95448).

Biología     Glosario (por ej. epibenthic)

Individuals of this species were found in groups; during the day they were commonly encountered below undercut river banks, especially in dense networks of tree roots or reed beds along the stream margins; places with shallow water and slow-flowing reaches of rivers and streams are especially attractive to them (Ref. 95448). Large numbers of small juveniles were found in bushes of aquatic reeds and floating grass on the periphery of the river or in side channels (Ref. 95448).

Estimates based on models

Phylogenetic diversity index (Ref. 82805):  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).
Nivel trófico (Ref. 69278):  3.1   ±0.4 se; based on size and trophs of closest relatives
Resiliencia (Ref. 120179):  Alto, población duplicada en un tiempo mínimo inferior a 15 meses (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (24 of 100) .
