Bothrops atrox — also known as the common lancehead, fer-de-lance, barba amarilla, [3] and mapepire balsain — is a highly venomous pit viper species found in the tropical lowlands of northern South America east of the Andes, as well as the Caribbean island of Trinidad. [2] No subspecies are currently recognized. [4]
The name fer-de-lance has been used inconsistently and very informally with several species in the genus Bothrops having been called fer-de-lance at one time or another, most commonly Bothrops asper, Bothrops atrox, Bothrops caribbaeus, and Bothrops lanceolatus.
Lacépède originally applied the name "lanceheads" [2] to all of these snakes, which he considered conspecific. Thus, older writings, as well as popular and sometimes scientific writings (including the American Heritage, Merriam-Webster, and New Shorter Oxford dictionaries), still often call them fer-de-lance (French, "spearhead").
After the fer-de-lance (Bothrops asper), it is the most common cause of snake envenoming. In the first half of the 20th century as well as in the 1950s and 1960s, 12% of treated cases ended fatally. In the first half of the 20th century as well as in the 1950s and 1960s, 12% of treated cases ended fatally.
Four species are venomous: two coral snake species (Micrurus spp. [note 1]), the fer-de-lance (Bothrops atrox) and the South American bushmaster (Lachesis muta). The common coral (Micrurus fulvius) is found on at least two of the Bocas Islands: Gaspar Grande and Monos. No venomous snakes inhabit Tobago.
Fer-de-Lance is French for spearhead (literally "iron of the lance"), and may refer to: Snakes of the genus Bothrops, especially: B. lanceolatus, the Martinique lancehead snake; B. caribbaeus, the Saint Lucia lancehead; B. atrox, the common lancehead, native to tropical South America east of the Andes and to Trinidad
Bothrops lanceolatus — known as the fer-de-lance, Martinican pit viper, [3] and Martinique lancehead [1] [4] [5] — is a species of pit viper endemic to the Caribbean island of Martinique. [ 1 ] [ 4 ] Some reserve the common name fer-de-lance for this species, while others apply that name to other Bothrops species, as well.
Including B. insularis and B. jararaca, 37 species are placed in the genus Bothrops, which are all native to South America. [3] Besides "lancehead", another common name for a snake in the genus Bothrops is "fer-de-lance". No mammals are native to the island Queimada Grande, which has undoubtedly had a profound impact on the evolution of the ...
