Edna: Your boy's suit I designed to withstand enormous friction without heating up or wearing out, a useful feature. Your daughter's suit was tricky, but I finally created a sturdy material that can disappear completely as she does.
Viper redirects here. For other uses, see Viper (disambiguation). The Viperidae (vipers) is a family of venomous snakes found in most parts of the world, excluding Antarctica, Australia, New Zealand, Madagascar, Hawaii, various other isolated islands, and north of the Arctic Circle. All have relatively long, hinged fangs that permit deep penetration and injection of venom.
Within much of its range, this species is easily the most dangerous viper snake and a major cause of snakebite injury and mortality. It is a member of the big four venomous snakes in India, which are together responsible for nearly all Indian snakebite fatalities. This snake grows to a maximum length of 166 cm (5.5 ft). The average length is about 120 cm (4 ft) on the mainland, although island populations do not attain this size.
