Biology     Glossary (e.g. epibenthic)

Is the largest in the Simochromis group. Adults inhabit rubble areas in shallow water, either solitary or in aggregation, most often not exceeding 5 m in depth and never exceeding 10 m. Adapted to murky water (Ref. 6770). Has a vegetarian menu (Ref. 7343). Females brood their young in the mouth (Ref. 86760).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Eggs from the cleavage phase and larvae of up to 1.56 cm TL are mouthbrooded by female parents 6.0 to 9.0 cm SL in size (Ref. 86760).

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=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic Level (Ref. 69278):  2.0   ±0.1 se; Based on diet studies.
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (22 of 100) .
