“At a trading station in Hainan Swinhoe (1870a p.229) (1) procured three skins and noted the difference between these and the skins of other otters , the minute pointless claws, toes longer and more fully webbed than in Aonyx, and the relatively long first toe of the hind foot. He believed that it was different from Malacca specimens in its longer tail and lack of a white throat. He adds that the bones of this otter found in caverns are ground by the Chinese and applied to wounds from poisoned arrows in order to absorb the poison. The natives in Hainan believe that this is a cross between the common otter and the gibbon and it is there known as “Mountain otter”. Anderson (1879, p.213) (2) records that he found otters of this genus in western Yunnan , in the hills to the eastward of Bhamo, Burma. Two skins that he procured seemed brighter colored than the average Micraonyx cinera.
Other than these, there are no definite records of the small-clawed otters in southern China” (3)
