was a Japanese zoologist, who is known for his work on the cephalopods of Japan, as well as other groups such as salamanders.[1] Sasaki was Professor of Zoology in the Fishery Department of the College of Agriculture at Tohoku Imperial University, Sapporo, Japan. Sasaki died in 1927[2] and his major work A monograph of the dibranchiate cephalopods of the Japanese and adjacent waters was published posthumously in 1929,[3] and was based largely on his studies of the cephalopod collections of the Zoology Department of the "Tokyo University Museum", many of which he collected himself.[2] The species Sebastodes sasakii, Octopus sasakii and Sepia sasakii are among the taxa that bear names that honour Sasaki.[4]
