Metlapilcoatlus is a genus of venomous pit vipers endemic to Mexico and Central America. Six species are currently recognized. The common names suggest they are able to leap at an attacker, but this is likely exaggerated. Common names for the species include jumping pitvipers and jumping vipers. The genus name comes from the Nahuatl name metlapilcohuatl, which means of the oblong grindstone held in the hand when grinding corn - alluding to the snakes short stocky body.
Bothriechis schlegelii, known commonly as the eyelash viper, is a species of venomous pit viper in the family Viperidae. The species is native to Central and South America. Small and arboreal, this species is characterized by a wide array of color variations, as well as the superciliary scales above the eyes. It is the most common of the green palm-pitvipers, and is often present in zoological exhibits. The specific name schlegelii honors Hermann Schlegel, who was a German ornithologist and herpetologist. For other common names see below. No subspecies are currently recognized as being valid.
Terciopelo is a highly venomous species of pit viper found at low to moderate elevations in northeast Mexico and Central America, and into South America where it is known from elevations up to 2600 meters in the Colombian and Ecuadorian Andes, as well as into 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 pit vipers. It is light to dark brown in color, often with yellow zig-zag-shaped lines on each side of the body. Dubbed "the ultimate pit-viper" for its large size, fangs and venom yield, it has a fearsome reputation, responsible for the most snakebites within its range because of its defensive temperament and proximity to human residence. However, like other venomous snakes, it avoids confrontation with humans whenever possible. No subspecies are currently recognized.
Bothriechis is a genus of venomous pit vipers, commonly called palm vipers or palm-pitvipers found predominantly in Mexico and Central America, although the most common species, B. schlegelii, ranges as far south as Colombia and Peru.

Porthidium is a genus of venomous pitvipers found in Mexico and southward to northern South America.

The snakes of the genus Hypnale in southern India and Sri Lanka look quite similar to those of this genus, possibly an example of convergent evolution.

The flora and fauna of Honduras reflects the country's geographical location inside the tropics. This has allowed for diverse species of plants and animals to be adapted, but some of them are now in danger of extinction. This has posed the Honduran government, offices and nature organizations to look after the protection of the local environment, like the creation of nature reserves.
