Snake in the Grass.
Warmtoast,
Your Bitis arietans looks a nasty piece of work ! Seems it has the same distinction as my krait, that of being the cause of more than any other snake bites in their respective lands.
Wiki says that the krait has the higher untreated mortality rate (70-80%), the Puff Adder >10% (but if it Bitises a bit harder, 52%). But your victim looks to have a harder time before he dies than mine.
Case of "you pays your penny, you takes your choice !", I suppose.
Danny.
