Biologie     Fachlexikon (Englisch) (z.B. 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 Geschlechtsreife | Fortpflanzung | Ablaichen | Eier | Fecundity | Larven

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 of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00977 (0.00375 - 0.02544), b=2.98 (2.75 - 3.21), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.5   ±0.45 se; Based on food items.
Widerstandsfähigkeit (Ref. 69278):  hoch, Verdopplung der Population dauert weniger als 15 Monate. (Preliminary K or Fecundity.).
Verwundbarkeit (Ref. 59153):  Low vulnerability (23 of 100) .
