Fejervarya triora
Encyclopedia
Fejervarya triora is a species of frog
belonging to the family Ranidae. It is only known from Phu Jong-Na Yoi National Park, Ubon Ratchathani Province
in the far east of Thailand
.
This is a robustly built frog, females having a body length of up to 60 mm (adult males are thus far unknown). The warty upperparts are olive brown with green blotches, the underparts are greyish white. There is an orange spot on the lower half of the tympanum
and yellow and black patterning on the legs. The iris
is bronze-coloured. When compared to other Fejervarya species found in the region, F. triora can be distinguished from F. raja
by its much smaller size and from both F. cancrivora
and F. limnocharis
by its broader head and the lack of distinct ridges along the back.
The tadpole
is mostly dark brown with a yellow line on the lower part of the tail and the front two thirds of the ventral fin pale.
