What is a puff adder?
The puff adder (Bitis arietans) is a large, venomous snake found in sub-Saharan Africa and the Arabian Peninsula. The name 'puff adder' comes from its defensive behavior of inflating its body and hissing loudly when threatened.
This snake has a stocky build, with adults typically reaching around 1 meter (3.3 feet) in length and weighing 4.5 to 6.8 kg (9.9 to 15 pounds). Their scales are dull-colored, ranging from sandy tan to gray or dark brown, with yellowish U- or V-shaped patterns on their backs, providing camouflage in their environment. They possess a flat, triangular head with fangs that can be as long as 5 cm (about 2 inches).
Puff adders are responsible for a significant number of snakebites in Africa each year, but fatalities are relatively rare. Their venom can cause pain, blistering, and tissue damage. They prey on rodents, small mammals, lizards, frogs, and birds, and they reach sexual maturity at age 4, breeding annually and producing 20–40 live young.

Where do puff adders live?
The puff adder (Bitis arietans) is a venomous snake found in sub-Saharan Africa's semiarid regions and the western and southern coastal areas of the Arabian Peninsula. Their scales range from sandy tan to gray to dark brown with yellowish U- or V-shaped patterns on their backs, allowing them to blend in with desert rocks, sand, and dry vegetation.
Puff adders are common throughout their range, except for a small, rare population in Morocco. They are often killed due to being viewed as dangerous pests.

How does the puff adder defend itself from enemies?
When threatened, the puff adder will inflate its body with air and hiss loudly to discourage predators from attacking puff adder. Their dull-colored scales provide camouflage against desert rocks, sand, dry twigs, and grasses. They may also remain motionless while predators search for them and can produce a chemical that renders them odorless.
Puff adders are preyed upon by larger predators, such as honey badgers, secretary birds, eagles and other birds of prey, and ground hornbills.

What does the puff adder eat and how does it catch its food?
The puff adder's diet consists primarily of rodents, small mammals, lizards, frogs, and birds. When hunting, the force of a puff adder's bite can be enough to kill its prey before its venom takes effect. The puff adder's dull-colored scales provide camouflage against rocks, sand, and dry vegetation.

Why is the puff adder considered a dangerous snake?
The puff adder is considered a dangerous snake because it is a large, extremely venomous snake species found in sub-Saharan Africa and the Arabian peninsula. The puff adder is responsible for more snakebite incidents than any other snake in Africa, numbering in the thousands annually. While its venom rarely causes death, it can cause pain, blistering, and tissue damage that may result in the loss of limbs. Its dangerous reputation may be overstated because its venom is relatively slow-acting, and fatalities are often related to other factors like infection. When threatened, the puff adder will inflate its body with air and hiss loudly.

puff adder, (Bitis arietans), large, extremely venomous snake species found in the semiarid regions of sub-Saharan Africa and the western and southern coastal areas of the Arabian peninsula. The species is named for its tendency to inflate its body with air and hiss loudly when threatened, in order to discourage predators from attacking it. Some 15 of the roughly 18 species classified in genus Bitis also engage in this behavior, and thus several sources refer to many of these as puff adders, including the Gaboon viper (B. gabonica) and the rhinoceros viper (B. nasicornis).
Form and function
The puff adder is a fairly large, stocky snake. Although the largest adults can grow as long as 1.5 meters (4.9 feet), most are rarely longer than 1 meter (3.3 feet) and weigh between 4.5 and 6.8 kg (9.9 and 15 pounds). The snake can be recognized by its dull-colored scales whose shades range from sandy tan to gray to dark brown and create yellowish U- or V-shaped patterns on its back. Its concealing coloration helps to camouflage it against desert rocks, sand and dry twigs, and grasses. The scales on its underside are lighter colored than those on its back. The snake also possesses a flat, triangular head with fangs that can be as much as 5 cm (about 2 inches) long.
The puff adder can kill with its venom; however, when hunting prey—which is largely rodents, other small mammals, lizards, frogs, and birds—the force of its bite when it strikes is often enough to kill its victim before its venom can take effect. Puff adders are preyed upon by larger predators, such as honey badgers, secretary birds, eagles, and other birds of prey, and ground hornbills. In addition to their coloration and menacing demeanor, puff adders also may also remain motionless while predators search for them and can produce a chemical that renders them odorless.

Puff adders are blamed for several thousand snakebite deaths in Africa each year, more than any other snake. Some sources, however, suggest that the snake’s dangerous reputation may be overstated. Whereas the puff adder is largely responsible for a significant number of snakebites on the continent, its venom rarely causes death, but it can cause blistering, pain, and tissue damage (which may result in lost limbs). Its venom is relatively slow acting, and thus death stemming from a puff adder bite is likely influenced by other factors, including infection at the site of the bite.
Puff adders become sexually mature by age 4, and adult snakes tend to breed annually between October and December The species is ovoviviparous (in that fertilized eggs are retained within the mother and young are born alive), and breeding females produce a clutch of 20–40 young. Young snakes are not cared for by either parent. While the life spans of puff adders are not well known in the wild, they can live as long as 15 years in captivity.
Conservation status
The puff adder is listed as a species of least concern by the International Union for Conservation of Nature and Natural Resources (IUCN). The species is common in all parts of its range except for a small population in Morocco, where it is considered rare. It tends to be viewed as a dangerous pest, and thus the snake is often killed in confrontations with people. Larger individuals may be harvested for their meat and venom.
