The Arrowhead Dogfish (Deania profundorum) is a deep-water shark species found in temperate and tropical oceans, recognized by its slender body, long snout, and distinctive arrow-shaped head. This species inhabits continental slopes and is typically caught at depths ranging from 200 to over 1,000 meters. The primary countries involved in the commercial harvesting of Arrowhead Dogfish are Spain, Portugal, and New Zealand, where deep-sea trawl and longline fisheries target various squalid sharks for their meat and, more commonly, their valuable liver oil. These nations have developed specialized deep-water fleets and have historically led the global landings of deepwater dogfish species, including the Arrowhead Dogfish, which is often caught as bycatch in mixed-species fisheries. The fishing industry for this species is relatively small compared to other commercial sharks, but it has raised concerns over sustainability due to the species' slow growth and low reproductive rates.
