Bitis arietans, commonly known as the puff adder, is a venomous snake found in various regions of Africa. It is characterized by its stout body, broad head, and distinctive zigzag pattern along its back. Puff adders are primarily nocturnal and are known for their excellent camouflage, which helps them blend into their surroundings. This species is notorious for its defensive behavior, often inflating its body and hissing loudly when threatened. The puff adder's venom is cytotoxic, causing tissue damage, and it is responsible for a significant number of snakebite incidents in Africa. Despite its dangerous reputation, it plays a crucial role in the ecosystem by controlling rodent populations.
