Bothrops pauloensis is a species of pit viper from Brazil, Paraguay and Bolivia - most commonly Cerrado. It is named specifically after São Paulo. As with all vipers, it is Venomous. Bothrops pauloensis displays stripes on the sides of its head behind the eyes as well as 11 to 25 blotches along the sides of its body. The colouration is highly variable, but it is often cream with black blotches. The placement of the blotches is also variable, but they are often distanced from each other.
The venom of Bothrops pauloensis has been researched for its toxins' possible therapeutic effects. Bothrops pauloensis is often in high altitude areas at 200–500 m (660–1,640 ft) with a high humidity and low temperature.
Bothrops pauloensis reproduces sexually and is ovoviviparous. Wikipedia →

Likely
About 50% of wildlife watchers report a Cerrado Lancehead sighting in Emas National Park on a given day, based on 33 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 2nd most-seen of the 11 reptiles we can rate there. Over three days the chance rises to about 90%, and over a week to over 90%, if each day is a fresh chance.
March–April and November–December
In those months about 70% of wildlife watchers report a Cerrado Lancehead in Emas National Park on a given day, against under 5% in July and September, the lowest months. Those are among Emas National Park's wettest months, with about 140 mm of rain a month against almost none in July.
Between 6 and 9 pm
Across all the parks we cover, that three-hour window holds the most Cerrado Lancehead sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is most active around dawn and dusk.
Only Emas National Park, in our data
Emas National Park is the only park on Wallace's Line with enough records to rate Cerrado Lancehead sightings: about 50% of wildlife watchers there report one on a given day.
Same genus: Bothrops
The closest relatives of the Cerrado Lancehead that you can see in Emas National Park (genus Bothrops, Neotropical Lanceheads) are Urutu Lancehead (about 40%) and Brazilian Lancehead (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Cerrado Lancehead is recorded against all the reptiles logged in Emas 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.
