Scientific name: Bitis arietans
Genus: Puff adders
Length: Up to 6.2 ft (1.9 m)
The puff adder likes to sunbathe on paths, doesn’t run away from people, and isn’t afraid to bite - as well as long teeth, this snake also has the strongest viper venom (and plenty of it, too). If a bite isn’t properly treated, the tissue around the wound can die so that the leg or arm has to be amputated.
