Ecology: This species inhabits stagnant or slow moving bodies of water with emergent-submergent vegetation (Uetz, 2012). During the dry season it will bury itself under the mud until the rainy season returns. It can be found in fresh, brackish, and sea water (Murphy et al. 2010). This rear-fanged aquatic snake feeds exclusively on fish, which is accomplished via an ambush method. It lives its entire life in murky water and can stay underwater for up to 30 minutes without coming up for air. It can move only awkwardly on land. In dry times and at night, the snake may burrow itself in the mud. The 5-13 young develop ovoviviparously (eggs hatch internally) and are born live underwater (Thiesen, 2012).
Means of Introduction: Pet release.
Status: A breeding population is not suspected.
Impact of Introduction: The impacts of this species are currently unknown, as no studies have been done to determine how it has affected ecosystems in the invaded range. The absence of data does not equate to lack of effects. It does, however, mean that research is required to evaluate effects before conclusions can be made.
