They can âbite and holdâ their prey or âbite and release,â 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 3â75% 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.2,25â28 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 (âcold-bloodedâ) prey as juveniles to based mostly on endothermic (âwarm-bloodedâ) 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 âwarningâ 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. With its warm, tropical climate, Ecuador is a perfect home for reptiles who love to relax and soak in the sun. 57 However, the venom’s toxic and enzymatic activities differ drastically between populations 35,58 and across age categories.

Etymology: The generic name Bothrops, which is derived from the Greek word bothros (meaning âpitâ),66 refers to the heat-sensing pits between the eyes and nostrils. British Wildlife is the leading natural history magazine in the UK, providing essential reading Males of Bothrops asper become sexually mature when they reach ~99.5 cm in total length; females at ~111.3 cm, or in little over 3 years,62 although females may attain a length of >2 m and a weight of 6 kg in just 2.5 years.63 The breeding season of some Fer-de-Lance populations coincides with the rainy season.2 Females are capable of delaying fertilization by storing sperm for years.2 After a gestation period of 6â8 months, females âgive birthâ (the eggs hatch within the mother) to 2â102 young1,49 that are 21.5â37.1 cm in total length.50,62 Females usually produce only one litter per year if environmental conditions are favorable.62 In captivity, individuals can live up to 21 years.2, Conservation: Least Concern Believed to be safe from extinction given current circumstances..64 Bothrops asper is listed in this category because the species is widely distributed, frequently encountered throughout its range, tolerates and even thrives in human-modified environments, and is considered to be facing no major immediate extinction threats.2 However, the Fer-de-Lance generally cannot survive in areas without vegetation cover.2 The substitution of traditional crops for mechanized agriculture is causing the species to be less frequently encountered or absent altogether in some areas.2,9 Other threats to the species include direct killing (terciopelos are usually killed on sight by humans alleging precautionary reasons),2,9,14 traffic mortality, and the decline in the abundance of prey.

In Ecuador, the Central American Lancehead (Bothrops asper) may be identified by having a triangular-shaped head with a snout that is not upturned, heat-sensing pits between the eyes and nostrils, and a dorsal pattern of 14â28 pale X-shaped markings on a brownish dorsum.1,2 Newborn lanceheads have brightly-colored tail tips (yellowish in males and pink/whitish in females).3 In Ecuador, the most similar species that may be found living alongside B. asper are B. punctatus and B. osbornei, which are identified by their dark brown trapezoidal blotches or spots arranged in such a way that they form squares.4 The Ecuadorian Toadhead (Bothrocophias campbelli) has an upturned snout and comparatively much smaller eyes.5 The hognosed-pitvipers (genus Porthidium) have an upturned snout and a stout body.
