Bitis peringueyi, also known as the Peringuey's adder, Peringuey's desert adder or desert sidewinding adder, is a viper species found in Namibia and southern Angola. No subspecies are currently recognized. Bitis peringueyi is a small snake with an average total length (including tail) of 20–25 cm (8–10 in), its maximum recorded total length is 32 cm (13 in).
The head is short and flat with eyes located on top of the head. The head is covered with strongly keeled scales, the smallest of which are located anteriorly. The eyes are separated by six to 9 scales, while each eye is surrounded by 10-13 scales. Two to four scales separate the suborbitals from the supralabials. The latter number 10-14, the sublabials 10-13. The one pair of chin shields contact the first two to four sublabials.
The dorsal scales number 23-31 at midbody and 21-27 anteriorly. All are strongly keeled, except those bordering the ventral scales are large and smooth. The ventrals number 117-144. The 15-30 subcaudals are usually keeled, particularly towards the tip. The anal plate is single.
The color pattern consists of a pale buff, chestnut brown to orange-brown, or sandy-grayish ground color, overlaid... Wikipedia →

Possible
About 20% of wildlife watchers report a Peringuey's Adder sighting in Namib-Naukluft National Park on a given day, based on 33 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 12th most-seen of the 39 reptiles we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
March, May, July, September and December
In those months about 30% of wildlife watchers report a Peringuey's Adder in Namib-Naukluft National Park on a given day, against under 5% in August, the lowest month.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Peringuey's Adder sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Namib-Naukluft National Park, in our data
Namib-Naukluft National Park is the only park on Wallace's Line with enough records to rate Peringuey's Adder sightings: about 20% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Peringuey's Adder is recorded against all the reptiles logged in Namib-Naukluft National Park (33 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.
