Kikuzato's brook snake (Opisthotropis kikuzatoi), also known commonly as Kikuzato's stream snake, is a species of snake in the family Colubridae. The species is endemic to Ryukyu Islands (Japan).
The specific name, kikuzatoi, is in honor of Kiyotasu Kikuzato, who collected the holotype. [3]
O. kikuzatoi is found on Kumejima Island, one of the Okinawa Group islands of Japan. [1] [2]
O. kikuzatoi is aquatic, inhabiting flowing streams in the northern and southern hilly regions of the island. Habitats between the two localities have been completely converted to agricultural land. [1]
This species, O. kikuzatoi, is listed as Critically Endangered by the IUCN under criterion B1ab(iii,v)+2ab(iii,v), due to threats from capturing as bycatch, water pollution, and predation from introduced species, primarily Lithobates catesbeianus, the American bullfrog. The American bullfrog was introduced was introduced to Kumeijima Island in 1953, and predation may provide great pressure on the population after many decades of population decline. Inbreeding within the small (and isolated) populations is becoming a significant threat also. Specimens have been observed with minor abnormalities (asymmetrical scales on the head) not recorded in the past. [1]
O. kikuzatoi feeds on earthworms, freshwater shrimp, freshwater fishes, tadpoles, and frogs. [2]

The wildlife of Cambodia is very diverse with at least 162 mammal species, 600 bird species, 176 reptile species, 900 freshwater fish species, 670 invertebrate species, and more than 3000 plant species. A single protected area, Keo Seima Wildlife Sanctuary, is known to support more than 950 total species, including 75 species that are listed as globally threatened on the IUCN Red List. An unknown amount of species remains to be described by science, especially the insect group of butterflies and moths, collectively known as lepidopterans.
The wildlife of Japan includes its flora, fauna, and natural habitats. The islands of Japan stretch a long distance from north to south and cover a wide range of climatic zones. This results in a high diversity of wildlife despite Japan's isolation from the mainland of Asia. In the north of the country, north of Blakiston's Line, there are many subarctic species which have colonized Japan from the north. In the south there are south-east Asian species, typical of tropical regions. Between these areas lies the temperate zone which shares many species with China and Korea. Japan also has many endemic species that are found nowhere else in the world, making it home to many endangered/rare species.

The yellow pond turtle, is a medium-sized, semiaquatic turtle in the family Geoemydidae. This species has a characteristic broad yellow stripe extending behind the eye and down the neck; the carapace ranges in color from grayish brown to brown, and the plastron is yellow or orange with black blotches along the outer edges. It is native to East Asia, ranging from central Vietnam and Laos, north through the coastal provinces of south and central China, with insular populations known from Taiwan, Hainan and the Ryukyu Islands. Although populations in the southern Ryukyus are thought to be native, populations in the northern and central Ryukyus, as well as central Japan, are believed to have been introduced as a result of imports from Taiwan.
