Eponymy: Charlotte Sclater was the wife of the zoologist William Lutley Sclater (1863–1944) (q.v.) who was Director of the South African Museum, and who presented the type to the British Museum (Natural History). (Ref. 128868), visit book page.

Environment: milieu / climate zone / depth range / distribution range
Ecology
Freshwater; demersal. Tropical; 11°S - 21°S
Africa: Okavango River, upper Zambezi River, Lake Kariba and the Kafue River (Angola, Namibia, Botswana, Zambia and Zimbabwe).
Length at first maturity / Size / Weight / Age
Maturity: Lm 11.3, range 10 - 12.5 cm
Max length : 34.5 cm SL male/unsexed; (Ref. 13337); max. published weight: 1.0 kg (Ref. 7248); max. reported age: 6 years (Ref. 7248)
Favors deep permanent floodplain channel and lagoons, with sandy bottom and vegetation (Ref. 7248, 52307). Feeds on aquatic insects, crustaceans and snails (Ref. 7248). Ovophilic, agamous (Ref. 52307) female mouthbrooder (Ref. 7248, 52307). Males construct a nest where the eggs are initially laid; mature at 10-12 cm length; useful snail control agent (Ref. 7248).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01862 (0.00904 - 0.03834), b=3.02 (2.85 - 3.19), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
Trophic level (Ref.
69278): 3.6 ±0.54 se; based on food items.
Generation time: 1.1 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
Resilience (Ref.
120179): Medium, minimum population doubling time 1.4 - 4.4 years (tm=2; tmax=5.5).
Fishing Vulnerability (Ref.
