The venom of the fer-de-lance is so potent that didelphine opossums (i.e., opossums like the Virginia opossum), which are normally immune to the venom of pit vipers and rattlesnakes, are still capable of succumbing to the venom of this snake. This is especially the case if the opossum is not fully grown (and thus the venom is more concentrated ...
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]
Several smaller islands lie off Trinidad, but snakes have been recorded on only one of them, Caledonia Island. Snakes have been recorded on one island off Tobago, Little Tobago. 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).

In Brazil and probably also in other countries in their area of distribution, this species is probably the most dangerous rattlesnake. 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.
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.
