Habitat and Ecology
Maximum total length (TL) is reported at 46 cm (Compagno et al. 2005). The mode of development of this species is uncertain, though the presence of a very thin-walled (rather than thick-walled) large egg-case in each uterus of the holotype suggests that the species may be ovoviviparous rather than oviparous, and if this is the case, the holotype is thought to have had two young in a litter (Compagno 1984).
From 70 to 170 meters.

IUCN Red List Assessment
Red List Category
Red List Criteria
The development and implementation of management plans (national and/or regional e.g., under the FAO International Plan of Action for the Conservation and Management of Sharks: IPOA-Sharks) are required to facilitate the conservation and management of all chondrichthyan species in the region.
Relevance to Humans and Ecosystems
The harlequin catshark (Ctenacis fehlmanni) is a species of finback catshark, part of the family Proscylliidae, and the only member of the genus Ctenacis. This shark is found in the western Indian Ocean off the coast of Somalia, at depths between 70 and 170 m. The 46 cm holotype was the only specimen that was ever found.
