Actinopteri (ray-finned fishes) > Centrarchiformes
(Basses) > Dichistiidae
Etymology: Dichistius: Greek, dichao, dichasis = divided in two parts (Ref. 45335). More on author: Cuvier.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 10 - ? m (Ref. 5213). Subtropical; 13°S - 36°S, 10°E - 34°E
Southeast Atlantic: southern Angola to Natal, South Africa.
Length at first maturity / Size / Weight / Age
Maturity: Lm 34.0  range ? - ? cm
Max length : 80.0 cm TL male/unsexed; (Ref. 4370); max. published weight: 6.5 kg (Ref. 4370)
Found in inshore reefs, rocky and sandy areas. Feeds on mollusks, crustaceans, and other invertebrates (Ref. 5213). Abundant in winter, breeding occurs in deeper water. Becoming scarce because of overfishing (Ref. 36731).
