Vipers' habitats vary across their nearly worldwide range. They live in mountains, rainforests, fields and deserts.
Generally, vipers are nocturnal. They often appear sluggish compared to other snakes, according to Nicolae Sfetcu, author of "Reptiles: Crocodiles, Alligators, Lizards, Snakes, Turtles" (Lulu Press, 2011).

The severity of a viper bite depends on the species and if it was a wet or dry bite, which contains no venom. Savitzky pointed out that European vipers (adders) have relatively moderate venom that is not highly lethal, while Gaboon vipers, which are found in sub-Saharan Africa, have highly potent venom. "Vipers in general tend to have enzymetic ven...
Most vipers are ovoviviparous, Savitzky said. That means the eggs are fertilized and incubate inside the mother and she gives birth to live young. "But," he added, "That is not true of some basal Asian pit vipers. And all New World pit vipers but one have live birth. That one is the Bushmaster viper and it has re-evolved egg laying." Vipers' mating...

May 27, 2024 · Vipers are highly venomous and are not native to the Americas. However, all is not lost! North, Central, and South America all have venomous snakes – they’re called pit vipers. Many of them have similar features to the Old World vipers – the stocky body, big angular heads, and retractable fangs.
Aug 3, 2020 · All species are venomous, although some are more dangerous than others. A viper’s venom is mostly hemotoxic, meaning that it acts on the blood, unlike the venom of elapid species, which is neurotoxic and affects the nervous system.
Vipera berus, also known as the common European adder and the common European viper, is a species of venomous snake in the family Viperidae. The species is extremely widespread and can be found throughout much of Europe, and as far as East Asia. There are three recognised subspecies.
Vipers are venomous snakes and are characterized by a pair of long, hollow fangs attached to bones of the upper jaw that enable them to inject venom into their prey when hunting. Almost all vipers have keeled scales, vertical pupils, and a triangle-shaped head due to the location of their venom glands behind their eyes.
The Crotalinae, commonly known as pit vipers, or pit adders, are a subfamily of vipers found in Asia and the Americas. Like all other vipers, they are venomous. They are distinguished by the presence of a heat-sensing pit organ located between the eye and the nostril on both sides of the head.
