Parturition of a rear-fanged rainbow water snake (Enhydrisenhydris) involved in snakebite and effects of its envenoming in Nepal.

ABSTRACT

Based on a specimen preserved in the snakebite treatment center in eastern Nepal, this study aims to analyse brief life history (i.e., litter size, parturition date, habitat preference) of Enhydris enhydris, effects of its envenoming, and anthropogenic threat on its populations. One euthanized gravid female E. enhydris collected alive from eastern Nepal by a snakebite victim was examined. The gravid female gave birth to 23 litters on July 11, 2012. This parturition suggested high reproductive potential. Its bite to a man walking on the road caused no ill-effects. However, the use of tourniquet as a part of prehospital care might be detrimental or be obstacle for in-hospital care of snakebite. The conflicts between E. enhydris and humans at roads and human-activity areas are inevitable across the distribution ranges of this species. The continued anthropogenic impact can threaten its populations. This study finding can be a basis for assessing conservation status and options for its conservation as well as prehospital care and prevention of its bites.
