Japanese Sawsharkノコギリザメ
Pristiophorus japonicusLC— Least Concern
The Japanese sawshark (Pristiophorus japonicus) is a small, nocturnal shark identified by its long, tooth-edged, saw-like snout, which it uses to injure or slice prey such as small fish, squid, and crustaceans on the seafloor. It lives on sandy or muddy bottoms of the northwestern Pacific around Japan, Korea, Taiwan, and China, from about 40 m down to 800 m deep, and is classified as Least Concern by the IUCN despite bycatch pressure from bottom trawling.
