I couldn’t find estimates for snakes and scorpions and completely ignored the invertebrates here, but from those options, Tigers kill the most humans yearly per wild individual.
There are about 5500 Tigers in the wild killing 50 humans yearly, while 115000 Hippos kill 500 humans yearly.
So Tigers kill 9 humans per thousand individuals, Hippos kill 4, next would be Lions with 2.5 .
Maybe they are the more deadly than Tigers on a per species basis since there are only 2 species of Hippo while 6 living species of Tigers exist… but then the other kill statistics would get a lot more precise as well. And I wont even try to analyze how often humans interact with specific animal groups.
