Abstract
The occurrence of the Japanese hooked squid Onykia loennbergii in the Arabian Sea is reported here based on reexamination of a previously collected and misidentified specimen in the course of research on oceanic cephalopods from the Arabian Sea. The individual’s dorsal mantle length (DML) measured 325 mm and it weighed 493 g. The individual was a mature male with a relatively long penis (165 mm) with 73 spermatophores. The current report forms the first confirmed report of the genus Onykia in the tropical Arabian Sea.
