Rate My Professor Keisuke Furumitsu

Keisuke Furumitsu is a researcher in the Laboratory of Marine Zoology at the Graduate School of Fisheries and Environmental Sciences, Nagasaki University. He holds a Doctor of Philosophy and serves in a postdoctoral or researcher capacity focused on ichthyology. His work centers on marine biological functions, with particular emphasis on elasmobranchs including stingrays and eagle rays.

Furumitsu has contributed to multiple peer-reviewed studies on the taxonomy, reproductive biology, age, growth, and embryonic development of various ray species. Notable collaborations include research with Atsuko Yamaguchi on the redescription of Hemitrygon akajei and the description of a new species in the genus Hemitrygon from Japanese waters, published in Ichthyological Research. He has also co-authored papers on a new species of eagle ray, Aetobatus narutobiei, and investigations into embryonic diapause in the Naru eagle ray. Additional studies address age determination using otolith sectioning and reproductive biology of species such as the shortspine spurdog. These efforts have advanced understanding of elasmobranch diversity and life history in Japanese marine environments, including the Ariake Sea. Furumitsu maintains an active research presence through affiliations documented on university laboratory listings and academic platforms such as ResearchGate.
