Short Description
Only shark with 5 pairs of gill slits and one dorsal fin [517]. Head broadly flattened and spatulate, snout elongated and usually longer than mouth width. Labial furrows very long, uppers reaching upper symphysis [517]. No color pattern, uniformly dark brown [517]. Caudal fin with a distinct subterminal notch.

Western Central Pacific: known from the holotype and only specimen taken from the Mindanao Sea, Philippines. Upon comparing, the holotypes of Apristurus herklotsi and this species are conspecific, thus, suggesting that Pentanchus is a senior synonym of Apristurus. But due to lack of verifiable specimens, herklotsi is tentatively retained in Apristurus. Source:
