16. Puff Adder (Bitis arietans)
LD50: 0.14
The Puff Adder inhabits African continent below Sahara region and a part of the Arabian Peninsula, where it is one of the commonest species. It prefers savannas and grasslands, so it is absent from African rainforest areas. Since it occupies a wide range of habitats, its coloration varies from region to region, but it is characteristic for its U-shaped stripes along the body. The name Puff Adder comes from snake’s habit to hiss very loudly when threatened as a warning signal, when it is ready to inflict a deadly bite fast.
