Red Necked Keelback Caught on a Night Herping Trip

Just a pic – wanted to share this Thailand snake before I forgot….

Rhabdophis subminiatus, Red-necked keelback. Venomous and dangerous.

A boy, 12 yrs old, in Phuket, Thailand was in the Bangkok hospital for 2 weeks after a bite from this snake. The venom specifically attacks the kidneys.

Once thought to be harmless – these snakes are now considered dangerous. Don’t have one as a pet…

Beautiful and dangerous…

One WHO (World Health Organization) publication about the management of venomous snake bites in Southeast Asia mentions the antivenin for Rhabdophis tigrinus in Japan as having some effect on the venom of R. subminiatus. I am not sure if this is strictly for R. subminiatus found in Japan, or not. Worth a try though if you can get them to send you some antivenin. Otherwise, there is no other option – there is no monovalent antivenin specifically for R. subminiatus.
