Etymology: The generic name Bothrops, which is derived from the Greek word bothros (meaning “pit”),66 refers to the heat-sensing pits between the eyes and nostrils. Figure 1: Individuals of Bothrops asper from FCAT Reserve, Esmeraldas province, Ecuador (); Cerro de Hayas, Guayas province, Ecuador (); Morromico, Chocó department, Colombia (); Cerro Blanco Protected Forest, Guayas province, Ecuador (); Las Balsas Reserve, Santa Elena province, Ecuador (); Buenaventura Reserve, El Oro province, Ecuador (); and Canandé Reserve, Esmeraldas province, Ecuador (). It was right up against the tree. The fer-de-lance, known in Spanish as barba amarilla (“yellow chin”), is a pit viper (subfamily Crotalinae)—i.e., distinguished by a small sensory pit between each eye and nostril. Spanish common names: Equis de la costa, equis, rabihueso (Ecuador); barba amarilla, cuatronarices (Colombia); terciopelo, barba amarilla, nauyaca (Central America). 1.9–11.2 mg/kg)35,36 in which the venom of juveniles is more lethal, hemorrhagic, and kills more quickly than that of adults.37–40 In humans, the venom typically causes intense pain, swelling, bruising, bleeding, blistering, defibrination (depletion of the blood’s coagulation factors), nausea and vomiting, numbness, impaired consciousness, fever, and necrosis (death of tissues and cells).41–45 In pregnant women, it may cause fetal death.46 In poorly managed or untreated cases, it can cause amputations, permanent complications and disabilities (6% of cases), and even death (in 5–7% of cases).47–49 The prognosis is usually bad for victims that reach a hospital over six hours after the bite and for those that use traditional medicine, especially if they were bitten by a snake longer than one meter in total length.45,50 Critically envenomated victims die from intracranial hemorrhage, acute renal failure, blood poisoning, or hemorrhagic shock.50–52 However, some bites to humans involve no envenomation at all (“dry bites”).11 Bothrops asper causes 44.5–100% of snakebites throughout its range,47,53,54 probably 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.30,44, “All the information which I have obtained concerning this reptile, wherever it is known, concurs in respect to the frightful effects of its bite. They can “bite and hold” their prey or “bite and release,” subsequently following the scent trail of the envenomated prey.12 As juveniles, they attract prey by means of moving their brightly colored tail as a lure.20 Terciopelos are opportunistic predators; they feed on almost any animal that is 3–75% of their body mass.2,21 Their diet includes primarily (69%) mammals (mostly rodents, but also rabbits, skunks, opossums, and even porcupines), but also amphibians (mostly frogs such as Leptodactylus labrosus, L. rhodomerus, Lithobates vaillanti, Pristimantis achatinus, Rhinella horribilis, and Smilisca phaeota, but also caecilians)9,22, lizards (whiptails, anoles, the microteiid Ptychoglossus gorgonae,1 and the worm lizard Amphisbaena alba),23 snakes (including Dipsas andiana,9 and members of their same species), birds, invertebrates (mainly centipedes,24,25 but also beetles, flies, hemipterans, ants, grasshoppers, and crayfish), fish,23 and carrion.2,25–28 When consumed, some toxic frogs cause the vipers to be sluggish and incapable of moving for nearly an hour.29 The diet of the Fer-de-Lance seems to shift from being based primarily on ectothermic (“cold-blooded”) prey as juveniles to based mostly on endothermic (“warm-blooded”) animals as adults.30,31 Individuals obtain water from their prey, from dew-laden surfaces, and bodies of water.2, Terciopelos rely on their camouflage as a primary defense mechanism.2 When threatened, some snakes flee, others give a “warning” by wiggling their tail against the leaf litter, and some just readily attack.2,5 Predators of Bothrops asper include snakes (such as Clelia clelia, C. equatoriana, and Drymarchon melanurus),2,9 mammals (such as peccaries, skunks, coatis, and raccoons),1,2 falcons, hawks, chickens, crabs, and spiders (particularly tarantulas).2,9 There are records of adult Terciopelos being attacked and severely injured by monkeys.32 The Fer-de-Lance is parasitized by ticks, parasitic worms, and protozoans.2,33,34, The Fer-de-Lance is a venomous species (LD50The median lethal dose (LD50) is a measure of venom strength.
