Elasmobranchii (sharks and rays) > Carcharhiniformes
(Ground sharks) > Scyliorhinidae
Etymology: Haploblepharus: Greek, haploos = single + Greek, blepharos = eyelash (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated. 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).

Morphology | Morphometrics
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).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Oviparous, laying 2 egg cases at a time (Ref. 11228). Embryos feed solely on yolk (Ref. 50449).
