Bothrops leucurus, commonly known as the whitetail lancehead or the Bahia lancehead, is a species of venomous snake, a pit viper in the family Viperidae. The species is endemic to Brazil. There are no subspecies which are recognized as being valid. A female owned by YouTuber Venom Central is over six feet long.
The specific name, leucurus, meaning "whitetail", is from the Latin words leucus (white) and urus (tail). The specific name, pradoi, of the junior synonym Trimeresurus pradoi, is in honor of Brazilian herpetologist Alcides Prado.
The color varies from tan to reddish-brown, the pattern varies, from darker and lighter spots, similar to light diagonal dorsolateral lines. It has 23 to 31 rows of dorsal scale of the medium body, the belly is yellowish or whitish in color with dark, brown or gray spots, and irregular spots on the sides. It is a snake with terrestrial behavior, growing on average in 250–1840 mm, mainly found in forests, arid, semi-arid, dry, humid and sub-humid regions.

Possible
About 20% of wildlife watchers report a Whitetail Lancehead sighting in Salvador on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 8th most-seen of the 12 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.
May and September
In those months about 40% of wildlife watchers report a Whitetail Lancehead in Salvador on a given day, against under 5% in April, August, October and December–February, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Whitetail Lancehead sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
Only Salvador, in our data
Salvador is the only city on Wallace's Line with enough records to rate Whitetail Lancehead sightings: about 20% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Whitetail Lancehead is recorded against all the reptiles logged in Salvador (9 verified sightings), 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.
