(Ground sharks) > Scyliorhinidae
Etymology: Haploblepharus: Greek, haploos = single + Greek, blepharos = eyelash (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; demersal; depth range 0 - 130 m (Ref. 5510), usually 40 - 130 m (Ref. 5510). Subtropical; 29°S - 35°S
Southeast Atlantic: Cape Agulhas to Natal in South Africa. There are two different forms of this species, the 'Cape' and 'Natal' types, which differ in coloration and habitat and might be geographic variants or two distinct species (Ref. 6782).

Morphology | Morphometrics
soft rays: 0. Southeastern Cape form: sandy brown with 7 reddish-brown saddles bordered by black, and numerous small, dark brown and white spots between saddles; white below (Ref. 5578). Natal form: body cream in color with darker brown saddles and irregular white spots; white below (Ref. 5578).
Found in inshore and offshore waters of the continental shelf, on sandy and rocky bottoms (Ref. 244). Feeds on bony fishes, crustaceans and cephalopods (Ref. 244). Oviparous (Ref. 50449). Caught by surf anglers (Ref. 244).
Oviparous, with 1 egg-case laid per oviduct (Ref. 244). Embryos feed solely on yolk (Ref. 50449).
