A general term for marine fish belonging to the Squalus genus of the Squalidae family in the Squalini order. The name "squalus" comes from the thick spines on the leading edge of the dorsal fin. In Kyushu, it is called kennooso or kenbuka. Its English name is spiny dogfish, emphasizing the presence of the spines. There are five species of dogfish in the waters near Japan. Of these, the spiny dogfish S. acanthias has the widest distribution, living in temperate to polar zones around the world. In the waters near Japan, it is found north of Choshi on the Pacific coast and north of Sanin on the Sea of Japan side. Source: Heibonsha World Encyclopedia, 2nd Edition Information |
