These yellow-spotted keelback (Xenochropis flavipunctatus) snakes are rear-fanged and do have venom, however there are no reported deaths from them. The snake would need to bite hard and chew the venom into wound for a minute or so in order to really envenomate a human. Not many humans are willing to let a strong biting snake do that. Don’t you be the first!
