[The Three Species Discovered and Their Characteristics]
・Striped Sakura Wrasse ( xml-ph-0000@deepl.internal
) A rare species of the family Pomacentridae collected near Okinawa Island. It features a yellow oblique band on its body side. This research proposed the new standard Japanese name "Tasuki Sakura-dai". The Okinawa Churaumi Aquarium, where a co-researcher is affiliated, displays the world's first live specimen.
・Tonkin flounder [ Pterygotrigla ( Otohime ) tagala ]
A fish of the family Scorpaenidae collected in Tosa Bay, Kochi Prefecture. It has a distinctive pattern featuring black spots and white dots on the inner side of its pectoral fins. Although previously known from Southeast Asia and the Philippines, this is the first report from Japan based on a specimen.
・Spear-toothed Gurnard ( Champsodon sagittus )
This species, belonging to the family Champsodontidae, was collected from the deep seas of southern Japan, including the Hyuga Sea off Miyazaki Prefecture, with a specimen collected in Okinawa Prefecture in 1978 and preserved at Kochi University serving as the primary record. Previously known only from the Indian Ocean and Australia, this represents the first record of the species in Japan and marks its northernmost known distribution. Characterized by a pointed snout and slender body, the new standard Japanese name “Yajiriwanigisu” has been proposed.
