S [13]. As a result, the present observations represent a new distributional record of this species. Polymixia sazanovi Kotlyar 1992 (Polymixiidae; Figure 4C): Many people of this species were observed employing BC in sandy bottoms of rocky areas at 603 m depth on the Ritto Seamount. This species was previously reported to exist only around the Kyushu-Palau Ridge, Atsumi Peninsula, Yoron-jima Island in the Amami Islands, Ishigaki-jima Island Scaffold Library Physicochemical Properties within the Yaeyama Islands, and in southern Taiwan [14,15]. The present observations represent a new distributional record of this species. Polymixia japonica G ther 1877 and Polymixia berndti Gilbert 1905 had been observed inside the exact same region within the present study, indicating that these related congeners can share their habitat. Coelorinchus hubbsi Matsubara 1936 (Macrouridae; Figure 4D), specimen No. KM#125PI 01, 246.7 mm TL: A single specimen was collected by the ROV in patchy sand bottoms of rocky regions at 431 m depth on the Shoho Seamount. This species has previously been reported to become distributed on the continental shelf; having said that, it was recorded for the initial time from a seamount far separated from the shelf. Laemonema robustum Johnson 1862 (Diversity Library custom synthesis Moridae; Figure 4G): Numerous folks of this species were recorded by ROV and AUV in rocky regions ranging from 380 to 500 m depths on the Ritto and Nikko Seamounts. This species was previously reported only around the Kyushu-Palau Ridge, Yokohama within the Kanagawa Prefecture, and Amamioshima Islands in Japanese waters. The present observations represent a new distributional record of this species. Physiculus rhodopinnis Okamura 1982 (Moridae; Figure 4I), specimen No. KM#132PI 03, 156.4 mm SL: This was just about the most abundant species recorded by ROV and AUV in rocky areas ranging from 380 to 500 m depths on the Ritto and Nikko Seamounts. This species was previously reported only on the Kyushu-Palau Ridge in Japanese waters. The present observations represent a new distributional record of this species. Physiculus yoshidae Okamura 1982 (Moridae; Figure 4J): Various men and women of this species have been observed in rocky regions at a depth of 31000 m around the Ritto and Nikko Seamounts, but with comparatively reduce abundance than that of P. rhodopinnis. This species was previously reported only around the Kyushu-Palau Ridge, inside the East China Sea, and southern Vietnam. The present observations represent a new distributional record of this species. Acanthonus armatus G ther 1878 (Ophidiidae; Figure 5A): A single person of this species was recorded by the ROV inside a sandy location at 2016 m depth around the Shoho Seamount. This species was previously recorded only in Suruga Bay in Japanese waters. The present observation represents its second locality record in Japan. Bassogigas gilli Goode and Bean 1896 (Ophidiidae; Figure 5B): Two men and women of this species have been recorded by the ROV in a sandy region at depths of 1917 m and 1919 m in the Ritto Seamount. This species was previously reported only in the Okinawa Trough in Japanese waters. The present observations represent a brand new distributional record of this species. Unidentified species, Chaunacops sp. (Chaunacidae; Figure 5F): A single person of this species was observed by the ROV in a rocky location at 1884 m depth with the Ritto Seamount. This species seems to be equivalent to Chaunacops coloratus (Garman, 1899), which can be primarily discovered inside the eastern Pacific Ocean [16,17]. Although specimens must be identified in the species level, fishes of this gen.
