Abstract / Introduction / Summary:
As many as nine adults of Conchoderma virgatum Spengler, 1789 (Cirripedia: Thoracica: Lepadiformes: Lepatidae), were found to be attached in a group to the right gill cavity of Takifugu stictonotus (Temminck and Schlegel, 1850) (Tetraodontiformes: Tetraodontidae), caught on 14 January 2011 in a set net installed in the southern Sea of Japan off Kasumi, Hyogo Prefecture, western Japan. This represents the first record of direct attachment of C. virgatum to the gill cavity of marine fish.
