Maturity: Lm ?  range ? - ? cm
Max length : 12.0 cm TL macho / no sexado; (Ref. 86866)

Biología     Glosario (por ej. epibenthic)

Blind fish which lives in caves (Ref. 86866), about (700)750-850 m above sea-level (Ref. 2801, 86866). Feeds on small crustaceans living in the caves and also on animals washed into the caves (Ref. 557), although this needs confirmation (Ref. 86866). Estimated longevity 9-14 years, but may exceed 15 years (Ref. 86866). Not closely related to any extant epigean species of the Congo region. Classified as `textbook and popular press fish' in Ref. 4537.

Life cycle and mating behavior Maturities | Reproducción | Spawnings | Egg(s) | Fecundities | Larva

Expels eggs in a more or less haphazard fashion, the substrate on which the species spawns must have crevices and pores into which the adhesive eggs can roll and be hidden so to prevent predation by its parents or other cave inhabitants.

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 1.0000   [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):  3.5   ±0.45 se; based on food items.
Resiliencia (Ref. 120179):  Alto, población duplicada en un tiempo mínimo inferior a 15 meses (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
