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.

So it is not easy to find the most venomous animal on Earth, since they have evolved to target different species.
