Etymology: Holohalaelurus: Greek 'Holos' meaning entire, referring to the lack of labial folds, and the genus Halaelurus, for which Holohalaelurus was proposed as a subgenus of by Fowler (1934).;  punctatus: Name most likely derived from Latin 'punctum' meaning small hole, dot or spot, referring to the many small spots covering the dorsal surface of this species (Ref. 75585).

Environment: milieu / climate zone / depth range / distribution range Ecologie

Western Indian Ocean: endemic to the subtropical and tropical waters of southwestern Indian Ocean, southern Mozambique, off Natal, South Africa and off Madagascar (Ref. 75585). Status of threat: a common catch in bottom trawls in Natal and southern Mozambique, yet, despite recent biodiversity trawl surveys in that region, not a single specimen has been collected from this area since 1972. ORI data sheets confirm that specimens collected between 1964 and 1972 were apparently abundant, particularly off Mozambique in May 1969, and off Durban in June 1971. The only specimens of this species that have been collected since this date have been those from Madagascar in the late 1980’s and early 1990’s (Ref. 75585).

Korte beschrijving Morfologie | Morfometrie

Dorsale stekels (totaal): 0; Dorsale zachte stralen (totaal): 0; Anale stekels 0; Anale zachte stralen: 0. A broad-headed, dwarf catshark with small dark brown spots closely set on a yellow-brown or orange-brown background; small black pores on underside of head and body; no labial furrows (Ref. 5578).

Biologie     Verklarende woordenlijst (b.v. epibenthic)

Found on the uppermost continental slopes (Ref. 244). Feeds on small fishes, crustaceans, and cephalopods (Ref. 5213). The adult males are larger than females, a characteristic unusual among sharks (Ref. 244). Manifests partial sexual segregation. Oviparous (Ref. 50449).

Life cycle and mating behavior Geslachtsrijpheid | Voortplanting | Kuitschieten | Eieren | Fecundity | Larven

Oviparous, with one egg-case laid per oviduct at a time. Embryos feed solely on yolk (Ref. 50449). Partial sexual segregation is manifested by greater number of males than females off Natal but not off southern Mozambique.
