This species found in a pond. Whether these species recognized as Indian common toad by many scientist. But i am confused that it have no charactisticts hard wart like Duttaphrynus melanostictus. Its body surface also soft. It may be young of Duttaphrynus melanostictus or another species under Bufo.
