The common lancehead is a highly venomous pit viper that lives in the tropical lowlands of northern South America and on the Caribbean island of Trinidad. It is one of the most common pit vipers in its range and is not endangered. Its venom disrupts blood clotting, which makes its bite especially serious.1

It is mostly found on the ground and prefers wet forests. In Trinidad it lives from sea level up to 940 m. It is also met in coffee and banana plantations, where it hunts rodents and where workers are often bitten.1

It mainly eats small mammals such as rodents and opossums, and birds, but also takes frogs, lizards, smaller snakes, fish, crayfish, centipedes and tarantulas. Larger prey is struck and released, then tracked down by its scent trail.1

Otú ị ga-esi mata ya

Ground colour is olive, brown, tan, grey or yellow, and rarely rusty.1
The body pattern is a series of blotches that often fuse into bands. The markings are X-like, which is why some local names refer to the letter X.1
The chin is pale yellow, and a dark stripe runs from behind the eye to the corner of the mouth.1
The irises are gold or bronze, and the tongue is black.1
Adults usually measure 75 to 125 cm in total length and are moderately heavy-bodied.1

A na-agwakọkarị ya na: It is often confused with Bothrops asper, which was once included in this species. Most authorities now consider B. asper to be a separate species. This confusion also makes reports of its maximum size unclear.1

Its venom is haemorrhagic, meaning it damages the lining of blood vessels and uses up the substances that allow blood to clot. Symptoms can include severe bleeding, kidney failure, abnormal clotting, blisters and necrosis (death of body tissue). Bleeding in the brain can also occur. Recovery from the clotting problem has been seen 14 to 30 hours after a bite.1

The bite is serious and can be fatal. Plantation workers are often bitten. Juvenile snakes have more lethal venom that kills more quickly, and people bitten by young snakes are more likely to develop the clotting problem. In a case reported in the Brazilian Amazon, the patient died of a stroke even after antivenom was given. A Mexican polyvalent antivenom tested against it had no effect on the clotting problem.1

It is easily agitated, and it can lie camouflaged for hours, nearly undetectable, then strike at high speed.1

Eziokwu

An enzyme called reptilase, or batroxobin, is taken from its venom and used in modern medical laboratories to measure fibrinogen levels and blood clotting. The enzyme is not affected by heparin.1

Although it is mostly terrestrial, it is an excellent swimmer and will climb trees when needed to reach prey.1

Females with developing embryos move in and out of sunlight to keep themselves and the embryos at a constant temperature.1

Venom yield averages 124 milligrams, but can reach 342 milligrams.1

Despite the large-scale destruction of rainforests, it is among the most numerous and common of pit vipers.1
