Best known from Jin Yong's wuxia novel 《
神雕侠侣》(The Return of the Condor Heroes), where
莽牯朱蛤 ("Mang-gu red toad") is a legendary creature whose blood confers immunity to poison. Some readers identify it with real red-bellied toads (Bombina) or the cinnamon frog, but there is no clean zoological match — honest best read is that this is a semi-fictional / literary creature name rather than a standard taxonomy term.
