From the IUCN website: "This species is relatively widespread and common
throughout its range, from southern Russia to China. Threats include bycatch in
gillnet and setnets. Although this shark is not a target species, it is
sometimes still eaten. It is also known to occur in rocky, un-fished, nearshore
areas off Japan, providing it with some refuges. This species is also commonly
found in aquariums in China and Japan. Although few data are available on the
