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

Southeast Atlantic: just west of Cape Agulhas to southern Natal in South Africa (Ref. 5578). This species is sympatric with Haploblepharus edwardsii in the southeastern Cape region but there is at least partial microhabitat separation between the two - Haploblepharus fuscus occurs inshore while Haploblepharus edwardsii occurs in deeper water offshore (Ref. 244).

Biology     Glossary (e.g. epibenthic)

Found close inshore on the continental shelf, often in shallow, rocky areas (Ref. 244). Feeds on lobsters, crabs and small bony fish (Ref. 5578). Oviparous (Ref. 50449). Readily kept in captivity (Ref. 244). Caught by shore anglers (Ref. 5578).

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5625   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00324 (0.00151 - 0.00695), b=3.10 (2.91 - 3.29), based on LWR estimates for this Subfamily-BS (Ref. 93245).
Trophic Level (Ref. 69278):  4.0   ±0.63 se; Based on food items.
Resilience (Ref. 69278):  Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100).
Vulnerability (Ref. 59153):  Moderate to high vulnerability (53 of 100) .
