Dorsal spines (total): 10; Dorsal soft rays (total): 18-19; Anal spines: 3; Anal soft rays: 13 - 14. Changes from black to silver almost instantly to blend with environment; occasionally mottled or with 7-9 crossbars (Ref. 4370).

Distribution Countries | FAO areas | Ecosystems | Occurrences | Introductions | Faunafri

Southeast Atlantic: southern Angola to Natal, South Africa.

Biology     Glossary (e.g. epibenthic)

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).

Bayesian length-weight: a=0.01625 (-0.18375 - 0.21626), b=3.00791 (2.89408 - 3.12174), based on LWR estimates for species & family-BS (Ref. 93245).
Trophic Level (Ref. 69278):  3.3   ±0.45 se; Based on food items.
Resilience (Ref. 69278):  Low, minimum population doubling time 4.5 - 14 years (K=0.13).
Vulnerability (Ref. 59153):  High vulnerability (60 of 100) .
