HUGE RIVER SERPENT

The Nyan is said to dwell in rivers of Bengal (North-East India, Bangla Desh) and Myanmar (Burma).  You will find it, legend avers, in rivers.  To eat, it likes elephants.  The monstrous reptile will wrap itself around the elephant and then devour it.  Bearing all this in mind, it is wiser to observe a nyan from a distance.
