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. No subspecies are currently recognized.[4][6]
Geographic range
Bothrops lanceolatus is generally considered endemic to the island of Martinique in the Lesser Antilles. Along with Bothrops caribbaeus and B. atrox, it is one of three Bothrops species found in the West Indies. The type locality according to Bonnaterre (1790:11) is "La Martinique".[2]
Description
It measures 1.50 to 2 m long (5 feet long). Its color is brown, black and gray.
Behavior
As ambush predators, Martinique lancehead typically wait patiently somewhere for unsuspecting prey to wander by. It is known to select a specific ambush site and return to it every year in time for the spring migration of birds. Studies have indicated these snakes learn to improve their strike accuracy over time.
Diet
All of the various species are carnivorous, and eat other animals. Their diet primarily changes based on how large the snake is and where the snake lives. Larger individuals can feed on larger prey, while smaller species must eat smaller prey items. Martinican pit vipers hunt rats, mice, birds, rabbits, lizards, frogs, snakes, bats, and more.
Reproduction
With few exceptions, crotalines are ovoviviparous, meaning that the embryos develop within eggs that remain inside the mother's body until the offspring are ready to hatch, at which time the hatchlings emerge as functionally free-living young. In such species, the eggshells are reduced to soft membranes that the young shed, either within the reproductive tract, or immediately after emerging.
Venom
The venom has toxins that can cause clotting, and bleeding in humans, as well as muscle damage and swelling.
Vexillological trivia
The species is depicted on the unofficial flag of Martinique, one of the few examples (the Gadsden flag and the First Navy Jack of the United States , and the Flag of Mexico being others) of snakes being depicted on flags.
