Species of shark
The Japanese spurdog (Squalus japonicus) is a dogfish, a member of the family Squalidae. It is found in the western Pacific Ocean – southeastern Japan and the East China Sea,[2] including the Republic of Korea, the Philippines, and the Arafura Sea.[3] It occurs in temperate and tropical waters along the continental shelf and slopes[4] and primarily feeds on teleost fish and squid.[2] It is caught as bycatch in commercial fishing, which has caused populations to decline.[5]
