Bothrops venezuelensis, or the Venezuelan lancehead, is a species of venomous snake in the family Viperidae. [1] It is endemic to South America. [2]
There is not much known about the dangerousness of the venom to humans, but potentially lethal envenoming is possible. The venom of B. venezuelensis contains procoagulants, [3] possibly also myotoxins and cytotoxic substances. [4] This species is associated with a high snakebite-related morbidity and mortality in Venezuela, there's a report of a patient bitten by a juvenile, he had local swelling, severe pain, endothelial damage, excessive fibrinolysis, and incoagulable blood within 1.5 hours after the bite. He also had AKI with macroscopic hematuria, fluid overload resulted in pulmonary edema, requiring intermittent ventilation and diuretic treatment with furosemide. [5]
It is found in Colombia and northern Venezuela.
The type locality is " 'Boca de Tigre', Serranía de El Avila, Distrito Federal, Venezuela ". [6]

The terciopelo is a species of pit vipers, found in Central to South Americas. At low to moderate elevations, its habitat ranges from northeastern Mexico to Colombian and Ecuadorian Andes, as well as Venezuela. With a mass of up to 6 kilograms (13 lb), and a maximal length of 2.5 metres (8.2 ft), the terciopelo is among the largest vipers. It is light to dark brown in color, often with yellowish, zig-zag patterning on either side of its body. Dubbed "the ultimate pit-viper" for its defensiveness, large size, fangs and potent venom yield, it has a fearsome reputation, responsible for the most envenomated snakebites within its range, largely due to its proximity to humans, livestock and pets. Nonetheless, like all venomous snakes, the terciopelo actively avoids contact with humans and larger animals, with bites generally only occurring when the snake is cornered, pursued, or threatened. No subspecies are currently recognized.
