Overview
A modest-sized catshark from deep waters of the Southwest Indian Ridge, this species is best understood through its family placement, regional record, and limited available species-level data. A small catshark, with cataloged maximum length just over half a meter; no additional species-specific marks are supported by the supplied evidence. Recorded from the southwestern Indian Ocean along the Southwest Indian Ridge; broader species-level distribution is not established in the supplied evidence.
The catalog places this species in marine waters and gives it a deepwater range, but the supplied evidence does not resolve a finer habitat account.
Why it matters: The species is tracked in WoRMS under record ID 1042809, which anchors the taxonomic record used for this entry.
