Open encyclopedia reference
Zhangixalus viridis (Okinawan green tree frog or green flying frog) is a species of frog in the family Rhacophoridae. It is endemic to the Ryukyu Islands, Japan, and known from Okinawa, Iheya and Kume Islands of the Okinawa Group. Zhangixalus amamiensis from the Amami Group was formerly included in this species as a subspecies. Zhangixalus viridis is no longer present on Yoron Island. Its disappearance from the island sometime after 1958 is attributed to habitat change (conversion of paddy fields to drier habitats) and an introduced predator, the Japanese weasel (Mustela itatsi). This is the first island-level extinction of a native amphibian in the Ryukyu Archipelago during modern times. Zhangixalus viridis is a moderate-sized rhacophorid frog (snout-vent length 65–84 mm (2.6–3.3 in)). The skin of the dorsum can be bright green or brown. There are disks on its toes for climbing. The ventrum is yellow or white in color. It is a common species in forests close to paddy fields and wetlands. It breeds in wetlands and paddy fields by larval development.
