Besides, the venom promoted soluble Terminal Complement Complex (sTCC) assembly. This snake is most commonly found in the forests though Latin America and even in the tropics of Asia. The Fer-de-Lance is not currently a species at risk. The venom of this species is hemotoxic, painful, and hemorrhagic (causing profuse internal bleeding). However, the Fer-de-Lance is responsible for the majority (44.5–100%) 47,53,54 of snakebites throughout its range because snakes of this species are perfectly camouflaged, abundant in agricultural areas, 11,49 have a high venom yield (up to 1,530 mg or 5–6 cc of venom per bite) 49,55 and toxicity, and have an aggressive self-defense behavior. Front Immunol 11(1079):1–3. The snake bit Bethune while he was doing conservation work in a jungle on Costa Rica's Osa Peninsula, Kellett said. Article  Geographic Range The common lancehead (also called "fer de lance") is found in the tropical regions throughout Central and South America. Biogeographic Regionsnearctic native Habitat The common lancehead is found throughout the forests of Central and South America. The ventral side is yellow, cream, or a whitish gray, with dark blotches that are more frequent closer to the posterior end. [19], Across its geographic range, this species varies greatly phenotypically. J Exp Med 187(3):329–339. When cornered or threatened, this species can be very defensive and may exhibit an S-coiled defense display. The Fer-de-lance has a triangular head that can be most commonly 1.2 to 2 meters in length. Google Scholar, An Z, Li J, Yu J et al (2019) Neutrophil extracellular traps induced by IL-8 aggravate atherosclerosis via activation NF-κB signaling in macrophages. This is true in the premontane forest in Costa Rica, the cloud forest of Guatemala and Mexico, or the lower montane wet forest in the Caribbean Region of Colombia and Ecuador. B. asper, together with Crotalus durissus, is the leading cause of snakebite in Yucatán, Mexico. PubMed Central  [2] This species is reported to occur from seven (Bolívar, Carchi, Chimborazo, Esmeraldas, Guayas, Los Ríos and Pichincha) of the fourteen provinces along the Pacific slope of Ecuador. J Clin Invest 94(3):1147–1155. Arthritis Rheum 53(4):609–612. The two sexes are born the same size, but by age 7 to 12 months, females begin to grow at a much faster rate than males. [2][18] These are among the most sexually dimorphic of all snakes. Platelets. 53(7):284–291. The fer de lance snake is the deadliest on the American continent, found in countries like Guatemala, Beliz, Honduras, Colombia, Ecuador, and Venezuela, although its presence in southern Mexico is the most well recognized. Southwestern Naturalist 62(1): 77-84.

On the Atlantic side, mating was observed in March, and births occurred between September and November. 38. To prevent water loss where they occur in drier regions, this species has more scales. There it is quite common in both wooded and open areas (Mattison, 1986). Google Scholar, Lisman T (2018) Platelet-neutrophil interactions as drivers of inflammatory and thrombotic disease. Fer-de-lance snake. The specific epithet, asper, which is a Latin word meaning "rough" or "harsh", may allude to the species' keeled dorsal scales.

Otero R, Tobón GS, Fernando Gómez L, Osorio R, Valderrama R, Hoyos D, Urreta JE, Molina S, Arboleda JJ. It has also been observed to eject venom over a distance of at least 6 ft (1.8 m) in fine jets from the tips of its fangs (Mole, 1924).

These snakes have a very sophisticated venom-delivery apparatus that seldom delivers a "dry bite." [2], B. asper occurs throughout the inter-Andes valleys of Colombia across the Caribbean coastal plain through central Venezuela north of the Orinoco as far east as the Delta Amacuro region. Very big females can reach lengths up to 2.5 metres (8.2 ft), although this is uncommon. From snake venom to ACE inhibitor — the discovery and rise of captopril. N Engl J Med 377(12):1119–1131. Am J Trop Med Hyg 52(5):419–426. In the Colombian states of Antioquia and Chocó, it causes 50–70% of all snakebites, with a sequelae rate of 9% and a fatality rate of 6% (Otero et al., 1992). https://doi.org/10.1016/j.cub.2012.07.029, Øvstebø R, Hellum M, Aass HC et al (2014) Microparticle-associated tissue factor activity is reduced by inhibition of the complement protein 5 in Neisseria meningitidis-exposed whole blood. https://doi.org/10.1111/jth.14438, Hottz ED, Bozza FA, Bozza PT (2018) Platelets in immune response to virus and immunopathology of viral infections.

According to Anywhere, a travel website, the fer-de-lance is one of the most menacing animals in Latin America and the most threatening snake in Central America. Reproduction is highly seasonal and in Costa Rica, reproductive cycles are tightly related to rainfall patterns. It is common for a large fer-de-lance bite to lead to this sort of reaction. [28], This species was once regarded as a subspecies of B. atrox and can still often be confused with it. Bothrops atrox — also known as the common lancehead, fer-de-lance, barba amarilla and mapepire balsain — is a highly venomous pit viper species found in the tropical lowlands of northern South America east of the Andes. Dürschmied, Daniel [corrected to Duerschmied, Daniel]. University of Chicago Press, Chicago, Illinois. Populations of Bothrops often referred to as Fer-de-lance on the island of Saint Lucia are Bothrops caribbaeus. A generalized ontogenetic diet shift occurs, with a higher percentage of ectothermic prey in juveniles, changing to a greater percentage of endothermic prey in adults, particularly small mammals. It is considered the most dangerous snake in Costa Rica, responsible for 46% of all bites and 30% of all hospitalized cases; before 1947, the fatality rate was 9%, but this has since declined to almost 0% (Bolaños, 1984), mostly due to the Clodomiro Picado Research Institute,[26] responsible for the production of snake antiophidic sera (which are also exported to other countries in Latin America and Africa) and scientific research on serpents and their venoms, as well as educational and extension programs in rural areas and hospitals. [2][12][13] Several herpetologist have preferred and argued to restrict the name fer-de-lance to the Martinique lancehead (Bothrops lanceolatus) from the Caribbean Island of Martinique but, popular usage has rarely recognized any distinction. Nat Immunol 19(4):27–341. Other large vipers are more inclined to escape when they feel attacked, but the terciopelo is more likely to strike. Immediate online access to all issues from 2019. In addition, in the blood exposed to B. lanceolatus venom, we detected IL-1β, IL-6 and TNF-α interleukins production. Larisa Kellett, spokesperson for Bethune's non-profit Earthrace, said his condition deteriorated and he had to be carried out of the jungle. Its large size and habit of raising its head high off the ground can result in bites above the knee. Toxicon 41(1): 19–22. The fer de lance (Bothrops Asper) is nocturnal and generally lives in humid forests. [5], The generic name, Bothrops, comes from the Greek words bothros and ops, which mean "pit" and "face" (or "eye"), respectively. Photo by: Al Coritz . This is the only Bothrops species that occurs on the island of Trinidad, although the situation there is complicated due to proximity of Trinidad to the Orinoco Delta where it may be sympatric with B. Toxicon 38(2):209–221. Nat Clin Pract Nephrol 3(3):164–170. When it feels agitated, the fer-de-lance may vibrate its tail—the buzz is audible—before striking. 2, pp. “I felt this bang in my calf and I knew straight away it was a snake, turned around and this fer de lance snake went crawling away from me. The fer de lance (Bothrops Asper) is nocturnal and generally lives in humid forests. The positive importance is that the snake is helpful with pest control for farmers and the venom shows promising uses as a medicine or drug. https://doi.org/10.3390/toxins9080244, Delafontaine M, Villas-Boas IM, Pidde G et al (2018) Venom from Bothrops lanceolatus, a snake species native to martinique, potently activates the complement system. The Bothrops asper delivers around 260 milligrams of venom per bite, and that’s just an average. FASEB J 33:Ib510–Ib510. The Fer-de-lance is known for being one of the most venomous snakes in the world, and this particular snake belongs to the viper family. In time the snake population grew at an alarming rate and they were forced to use drastic measures. 411-420 Thus, inhibiting inflammatory mediators or their receptors may help in the envenomed patients’ management. FASEB J 30(5):1987–1999.

When it feels agitated, the fer-de-lance may vibrate its tail—the buzz is audible—before striking. Krieger Publishing Co. Malabar, Florida. Herpetologist Douglas March died after being bitten by this species. There is a great variety of colours on its dorsal side: olive, gray, light brown to dark brown, tan or sometimes nearly black.
