What is a key difference between African *Thelotornis* venom and that of their Asian counterparts like *Ahaetulla*?

Answer

Asian species venom is generally considered mild in comparison, typically causing only localized pain or swelling.

Asian vine snakes (*Ahaetulla*) are rear-fanged like their African relatives, but their venom is significantly less dangerous, usually resulting only in localized pain and not being reliably associated with human fatalities.
