Bushmaster — Lachesis (Bushmaster) is a genus of venomous pit vipers found in the remote, forested areas in Central and South America. The generic name refers to one of the Three Fates in Greek mythology; Lachesis determined the length of the thread of life. Three species are currently recognized.
Adults vary in length from 2 to 2.5 m, although and some may grow to as much as 3 m. The largest known specimen was just under 3.65 m, making it the longest venomous snake in the Western Hemisphere. This is also the longest viper, though not the heaviest (it is surpassed by the gaboon viper and the Eastern diamondback rattlesnake).
Lachesis is the only neo-tropical pit viper that lays eggs: about a dozen in the average clutch. The female is reported to remain with the eggs during incubation and may aggressively defend the nest if approached. The hatchlings average 30 cm in length and are more colorful than the adults.
One of the largest and most dangerous snakes in South America, the Bushmaster is capable of multiple bite strikes, injecting large amount of venom and even the bite of a juvenile Bushmaster can be fatal.
