This list of mythical creatures that begin with this letter and I am constantly gathering information from each continent, and is continually being updated.
Bashe (Chinese)
Bashe was a python-like Chinese mythological giant snake that ate elephants. It was graphically simplified from ancient Oracle bone script and Seal script pictograms of a long-tailed snake. In early Written Chinese usage, ba frequently referred to the Zhou Dynasty state of Ba, which was located in present-day eastern Sichuan.
Bashe not only names this mythical giant reptile or Chinese dragon but is also a variant Chinese name for the South Asian ran or mang "python" (and South American "boa constrictor" or African "mamba"). Since pythons usually crush their prey and swallow them whole, one can imagine Chinese tales about southern ran 'pythons' being exaggerated into legendarily-constipated bashe 'giant snakes' that ate an elephant every three years.
