Amphiesma pryeri — a non-venomous medium-sized snake from the Colubridae family. It lives near streams and in forests on the Ryukyu Islands in Japan.
Amphiesma pryeri differs from related keelback snakes by its special pattern of light stripes on a dark background and its strong association with water bodies. It regulates the number of frogs and maintains balance in the nature of the islands.
Immature form that undergoes metamorphosis before adulthood.
