Odorrana amamiensis (Matsui, 1994)
Amami Hanasakigaeru, Amami Tip-nosed Frog
© 2005 Timothy Johnson (1 of 1)
R. amamiensis frogs have a dorsal color ranging from light brown to greenish, with some individuals lacking dark dorsal markings. The dorsum has tubercles on the sacrum, while the side of the trunk is coarsely granular, and the chest and abdomen are smooth. There is a feeble dorsolateral line formed by short ridges. The supratympanic folds are weak.
R. amamiensis is similar to R. narina in that the inner side of the dorsolateral fold is usually lighter than the ground color. (This condition is never seen in the remaining species of the Rana narina group.) However, R. amamiensis is much larger than R. narina. There is no other large frog within its range that has such a long snout with nostrils at the tip.
