The puff adder (Bitis arietans) is a highly venomous viper species found in savannahs and grasslands from Morocco and western Arabia throughout Africa except for the Sahara and rainforest regions. It is responsible for causing the most snakebite fatalities in Africa owing to various factors, such as its wide distribution, frequent occurrence in highly populated regions, and aggressive disposition. Two subspecies are currently recognized, including the nominate subspecies described here.
The species is commonly known as the puff adder, African puff adder, or common puff adder. German naturalist Blasius Merrem described Bitis arietans in 1820. The specific name arietans means "striking violently" and is derived from the Latin arieto. The type locality given is "Promontorio bonae spei " (Cape of Good Hope), South Africa.
The puff adder's usual size is about 1.0 m (39.3 in) in total length (body and tail) and very stout. Large specimens of 190 cm (75 in) total length, weighing over 6.0 kg (13.2 lb) and with a girth of 40 cm (16 in) have been reported. Specimens from Saudi Arabia are not as large, usually no more than 80 cm (31 in) in total... Wikipedia →

Possible
About 20% of wildlife watchers report a Puff Adder sighting in Kruger National Park on a given day, based on 117 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 14th most-seen of the 62 reptiles we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
January–July and November
In those months about 20% of wildlife watchers report a Puff Adder in Kruger National Park on a given day, against about 10% in August–October and December, the lowest months.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Puff Adder sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
8th of 15
Of the 15 parks where we can rate Puff Adder sightings, Kruger National Park ranks 8th at about 20%. The best odds are in West Coast National Park (South Africa, about 50%), De Hoop Nature Reserve (South Africa, about 40%) and Tsavo East National Park (Kenya, about 30%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Puff Adder is recorded against all the reptiles logged in Kruger National Park (117 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
