Habitat

Inhabit moist forest and agricultural soil. A good swimmer. May frequent swamps, rice fields, drainage ditches; also in brackish water.

Behaviour Nocturnal. Fossorial, tunnelling through damp soil or resting with coiled body under rocks or rotten debris.
When disturbed, conceals its head among the body coil, flattens the tail and arches it upward to display its red pattern.
This is understood to be a warning display mimicking that of Coral Snake such as Sinomicrurus macclellandi.
Diet Fishes, particularly eels, frogs and small snakes. Kills by constriction.
Reproduction Viviparous, bearing up to 12 youngs. 17 cm at birth.
Distribution This species was previously considered not to occur in China or Hong Kong, as its main distribution is Southeast Asia.
However, two specimens were recorded around Xiamen in Fujian Province in 1960s.
Also, two young specimens were located in museums: one from Hainan and one from Hong Kong. Both were collected in the mid-1880s.
The Hong Kong specimen has not field data.
This local record may be valid as this snake is confirmed to occur in southern China.
This snake may probably occur in very few remaining local freshwater wetland.
Range from Southeast Asia and Indonesia, and China.
Conservation Status IUCN Redlist: NE (Not Evaluated)
