長澤和也・酒井恭平・河津優紀

Abstract / Introduction / Summary:

An ovigerous female of the cymothoid isopod Elthusa moritakii Saito and Yamauchi, 2016 was collected from the branchial cavity of a deep-sea fish Ereunias grallator Jordan and Snyder, 1901 (Scorpaeniformes: Ereuniidae), in Suruga Bay, an inlet of the western North Pacific Ocean, Shizuoka Prefecture, central Japan. The infected fish was incidentally caught by commercial deep-water trawling. The female collected slightly differs from the original description of E. moritakii in the shape of the cephalon and the position of the maximum body width. This collection of E. moritakii represents the second record of the species from Suruga Bay.
