Huanren Frog, Korean Stream Brown Frog
© 2012 Todd Pierson (1 of 3)
Dorsal coloration is greyish, brown, brown-olive, or olive for Rana huanrensis . Dark spots may or may not be present (Kuzmin 1999). The male ventral color pattern is yellowish-gray, with tiny black dots covering the throat and chest. Females also have the tiny black dots covering the throat and chest, and during breeding season, the female ventral color is yellowish-green (Kim et al. 2002). In contrast, the sympatric species R. dybowskii can be distinguished by a milky white venter in males and red throat and chest patches in females (Kim et al. 2002).
