Etymology: Haploblepharus: haplos (Gr.), single or simple; blepharon (Gr.), eyelid, referring to simple structure of lower eyelid, which closes against upper eyelid to protect the eye. (See ETYFish); fuscus: Latin for dusky, dark or swarthy, probably referring to its overall drab-brown coloration. (See ETYFish).

Ecologia
marinhas associadas(os) a recifes. 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).

Descrição suscinta
Morfologia | Morfometria
Espinhos dorsais (total): 0; Raios dorsais (total): 0; Espinhos anais 0; Raios anais : 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).
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).
