Etymology
The specific name, leucurus, meaning "whitetail", is from the Latin words leucus (white) and urus (tail).Wright AH, Wright AA (1957). Handbook of Snakes of the United States and Canada. Ithaca and London: Comstock Publishing Associates, a division of Cornell University Press. 1,105 pp. (in 2 volumes). ("English equivalents of Latin names", p. 3).
The specific name, pradoi, of the junior synonym Trimeresurus pradoi, is in honor of Brazilian herpetologist Alcides Prado.Beolens B, Watkins M, Grayson M (2011). The Eponym Dictionary of Reptiles. Baltimore: Johns Hopkins University Press. xiii + 296 pp. {{ISBN|978-1-4214-0135-5}}. (Bothrops pradoi, p. 210).
Description and Behavior
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.{{cite web|url=https://www.acq.osd.mil/eie/afpmb/docs/lhd/venomous_animals_byspecies.pdf|title=Living Hazards Database (LHD) – Search by Scientific Name|website=Acq.osd.mil|access-date=17 March 2022|archive-date=2 July 2017|archive-url=https://web.archive.org/web/20170702174255/https://www.acq.osd.mil/eie/afpmb/docs/lhd/venomous_animals_byspecies.pdf|url-status=dead}} 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.
Geographic range
Bothrops leucurus is found in eastern Brazil along the Atlantic coast from northern Espírito Santo north to Alagoas and Ceará. It occurs more inland in several parts of Bahia. The identity of disjunct populations west of the Rio São Francisco is uncertain. The type locality is listed as "provinciae Bahiae". It inhabits both urban and rural areas.{{Cite journal|last1=Grego|first1=K. F.|last2=Alves|first2=J. a. S.|last3=Albuquerque|first3=L. C.

Reproduction
Bothrops leucurus is viviparous. The gestation period is four months, and a medium-sized litter is 19 young, birth occurs between winter and summer.{{Cite journal|last=Lira-da-Silva|first=Rejâne Maria|date=2009-04-08|title=Bothrops leucurus Wagler 1824 (Serpentes, Viperidae): natural history, venom and envenomation |url=http://www.gmbahia.ufba.br/index.php/gmbahia/article/view/997 |journal=Gazeta Médica da Bahia |volume=79 |issue=Supl. 1 |pages=56–65 }}
Diet
It feeds on rodents, lizards, amphibians, snakes and birds (Martins et al., 2002).{{Citation|title=Summary identification charts: lizards and snakes|date=2011-12-31|url=http://dx.doi.org/10.1515/9780691206813-010|work=Britain's Reptiles and Amphibians|pages=36–38|place=Princeton|publisher=Princeton University Press|doi=10.1515/9780691206813-010|isbn=978-0-691-20681-3|access-date=2020-09-15|url-access=subscription}} with adults feeding on rodents, and juveniles feeding on frogs and lizards.
Venom
The whitetail lancehead is responsible for the most bites in the state of Bahia. The venom contains high fibrinolytic, proteolytic, hemorrhagic and edematogenic activity, and low coagulant activity, which can cause myonecrosis in humans. Symptoms include local pain, edema, erythema and ecchymosis (local symptoms), hemorrhagic and coagulation symptoms, digestive disorders (nausea, vomiting and diarrhea), urinary disorders (oliguria, anuria, hematuria) with headaches, dizziness, hypotension, bradycardia, visual disturbances and tremors.
