Ecology and description

Yaeyama yellow pond turtle is a subspecies of the yellow pond turtle (Mauremys mutica), found on Ishigaki, Iriomote, and Yonaguni. As of 2018, the yellow pond turtle was classified as CR (Critically Endangered) by the IUCN and requires protection.

Yaeyama yellow pond turtle is designated as a rare wild species of Okinawa Prefecture, yet it is considered a non-native species in the Okinawa Islands, the Miyako Islands, and the Daito Islands. On Miyakojima, Yaeyama yellow pond turtle could potentially prey on the local rare species Miyako freshwater crab (Geothelphusa miyakoensis).

The nominotypical subspecies of the yellow pond turtle are distributed in regions such as northern Vietnam, southern China, and Taiwan, with some non-native populations on certain Okinawan islands, likely originating from escaped captive individuals.
