This small catshark is apparently endemic to the Philippines (off Luzon), at depths of 329–431 m, with one record on the outer shelf at 50 m depth. The Dwarf Sawtail Catshark (Galeus schultzi) would be vulnerable to capture in trawl fisheries, although no information is available on its capture. Trawl fisheries are not thought to operate within this species’ main bathymetric range at present, however, its apparently limited range could make it vulnerable to depletion if fished. Insufficient information is available on this species’ biology, habitat, range and on potential threats to assess it beyond Data Deficient. The situation should be monitored carefully if fisheries expand into greater depths in the future.

|Population:||Known from only few records (Compagno et al. 2005b).|
|Current Population Trend:||Unknown|
|Habitat and Ecology:||This benthic, deepwater shark occurs on continental slopes at depths of 329–431 m, with one record on the outer shelf at 50 m depth (Compagno et al. 2005a). Females mature at 27–30 cm and males at ~25 cm (Compagno et al. 2005a). The species reaches a maximum size of 30 cm (Compagno et al. 2005a). Little else is known of the biology of the species.|
|Major Threat(s):||This species would be vulnerable to capture in trawl fisheries, although no data are available on its capture. Trawl fisheries are not thought to operate within this species’ main depth range off the Philippines at present (B. Séret pers. comm.).|
No management or conservation efforts are currently in place. Like many deeper water species more information on biology, ecology and importance in fisheries are required to further assess status and any future conservation needs. Further surveys would benefit the collection of data on the wider range of this species. If deep water fisheries develop in the future, catches will require careful monitoring.
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.
