First records of Callogobius tanegashimae in Wakasa Bay, the Sea of Japan coast of central Japan

Abstract

Two specimens of Callogobius tanegashimae (20.4 and 56.8 mm in standard length), collected from a muddy bottom in Wakasa Bay (bordering Fukui and Kyoto Prefectures), represent the first records of the species from the Sea of Japan. One specimen was collected with an alpheid shrimp using a yabby pump, suggesting that the goby may utilize shrimp burrows. The specimens are described in detail and their identification confirmed by reference to sequence variations on the mitochondrial DNA COI region (595 base pairs).
