Africa: endemic to Makokola in the southeast arm of Lake Malawi.

Biology     Glossary (e.g. epibenthic)

Inhabits the rocky biotope of the reefs, where the rocks are permanently covered with a layer of sediment. Feeds mainly from the phytoplankton in the open water. Territorial males feed from the biocover on the rocks (Ref. 5595). Oviparous (Ref. 205).

Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01570 (-0.15264 - 0.18405), b=2.97 (2.88 - 3.06), based on LWR estimates for this family-BS (Ref. 93245).
Trophic Level (Ref. 69278):  2.0   ±0.00 se; Based on food items.
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (15 of 100) .
Price category (Ref. 80766):   Unknown.
