Habits and Lifestyle

In general, this species is aquatic, active at night and occasionally in cloudy or drizzling weather, moving in shallow water and banks, or resting with its eyes only upward and the nose above the water. This snake is also able to climb mangrove trees, although it prefers to roam the ground. When inactive, take shelter between mangrove roots, dive under rubble or holes on the banks.

Population threats​

This species has historically been collected for its skin in the Philippines (Gaulke 1998). But, it is no longer being collected for skins in the Philippines (J. Gatus pers. comm. 2009). In 1993 it was reported that 775,000 skins were found in the leather trade in Indonesia (Lilley 1993). It is unclear if there is continued use of the species for leather in Indonesia.

Population number​

This species has a wide distribution and is abundant in many of its localities across the range. This species thrives in human areas such as fishing villages. There has been historic collection of this species for skins but this apparently no longer happens. This species has therefore been listed as Least Concern.
