Abstract / Introduction / Summary:
An ovigerous female and an adult male of the cymothoid isopod Ceratothoa verrucosa (Schioedte and Meinert, 1883) were found in the buccal cavity of a crimson seabream Evynnis tumifrons (Temminck and Schlegel, 1843) purchased in the fresh fish section of a supermarket in Fukui City, Fukui Prefecture, central Japan. The crimson seabream harboring these isopods was commercially caught in the Northwestern Pacific Ocean off Chiba Prefecture, central Japan, and transported to Fukui City. The present collection of C. verrucosa represents the first record of the species from crimson seabream on the market.
