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 ).

Maturity: L m   ?   range ? - ? cm
Max length : 69.0 cm TL male/unsexed; (Ref. 244 ); 73.0 cm TL (female)

Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 0; Anal spines : 0; Anal soft rays : 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 ).

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 ).

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 ).

Estimates of some properties based on models

Preferred temperature (Ref. 115969 ): 17.1 - 23.4, mean 20.8 (based on 49 cells). Phylogenetic diversity index (Ref. 82805 ):  PD 50 = 0.5625   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.00316 (0.00159 - 0.00631), b=3.12 (2.95 - 3.29), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (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 (54 of 100) . Price category (Ref. 80766 ):   Low .
