Abstract: In late May, 2014, Aplysia (Varria) kurodai and Dollabella auricularia (Mollusca) appeared at only night, changing from former behaviour of these species, probably showed an intrinsically nocturnal characteristics after spawning season is over at wharf of the Seto fishing harbor, Shirahama, Wakayama, Japan.
2014年5月下旬, 和歌山県白浜町瀬戸漁港のコンクリート製の船揚場の浅所(水深数m以内)でアメフラシとタツナミガイは産卵期を過ぎると夜間のみ出現する行動に変化した. つまり, 出現初期には太陽光の照りつける岸壁の浅所に産んだ卵塊と共に昼間に居残っていたが, 本来の夜行性にもどったと推察される.
