Ecologia
marino associati a barriera corallina. Subtropical; 30°S - 35°S
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).

Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 0; Spine anali: 0. The largest shyshark, usually plain yellowish-brown above becoming just yellowish below; small light spots and indistinct brown saddles in some specimens (Ref. 5578).
Body shape (shape guide): elongated.
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).
