Despite their name, these snakes do not actually spit their venom. They spray the venom, using muscular contractions upon the venom glands. These muscles squeeze the glands and force the venom out through forward facing holes at the tips of the fangs. As the venom leaves the fang tip, a large gust of air is expelled from the lung which aerosolizes the venom and propels it forward. When cornered, some species can "spit" their venom a distance as great as two meters. While spitting is typically their primary form of defense, all spitting cobras are capable of delivering venom through a bite as well. Most species' venom exhibit significant hemotoxic effects, along with more typical neurotoxic effects of other cobra species.
