Straight from Wikipedia:
Over 450 snakes were used for filming to represent thirty different species of snakes.[54] The different species include a 19-foot Burmese python named Kitty (which the crew named Kong for film purposes), a Scarlet Kingsnake (the non-venomous double for the coral snake), a milk snake to fill in for the Taipan (which attacks the couple having sex), corn snakes, rattlesnakes, and mangrove snakes.[55] About two-thirds of the snakes seen throughout the film were either animatronic or computer generated.[56] The snakes that were real were mostly the non-venomous ones that are never seen attacking anyone per se. The scenes where someone is clearly bitten were often done with the most animation. According to the DVD, "all" the snakes had production names, but only "Scarface" (an animated pit viper), "Peanut" (a cobra) and "Kong" are mentioned by name in the audio commentary.

COBRA:
Not all cobra bites are venomous; some bites are so called dry bites which may cause serious infections due to bacteria from the cobras mouth. It is estimated that approximately 75 % of people receiving a bite from a Cobra Snake will eventually die from the medical complications arising from the bite. A real (not dry) bite from a cobra snake will in the most severe cases cause death within 10 minutes.
RATTLESNAKE:
The purpose of the rattlesnake bite is to stun or put an immediate end to its prey. If a potential prey escapes a bite a rattlesnake will hunt it down and eventually make it pass away by force. Usually the snake is helped by its prey getting gradually more and more weakened due to the toxicity of its venom. Rattlesnakes are capable of regulating the amount of venom they inject when biting. If only feeling threatened the snake may not deliver a full dose of venom into the perceived attacker. A frightened or injured snake may not able or in the mood of exercising such a control. The same goes with young inexperienced rattlesnakes.
Mortality:
While there are many factors influencing the outcome in victims of snake-bite, there is an overall agreement in the case fatality rate - generally varying from 2-10%[16,47-51]. The mortality rate is higher in children owing to larger amount of toxin per kg body weight absorbed [27]. There is significantly higher mortality among victims who develop neurotoxicity [47,51]. On an average - cobras and sea snakes result in about 10% mortality [28]-ranging from 5-15 hours following bite. Vipers have a more variable mortality rate of 1-15% and generally more delayed (up to 48 hours) [22].
Deadliest Snake:
1) Fierce Snake or Inland Taipan (Oxyuranus microlepidotus ), Australia. The most toxic venom of any snake. Maximum yield recorded (for one bite) is 110mg. That would porbably be enough to kill over 100 people or 250,000 mice. With an LD50 of 0.01 mg/kg, it is about 10 times as venomous as a Mojave rattlesnake and 750 times as venomous as a common cobra. The Fierce Snake is native to the arid regions of central Australia, extending from the southeast part of the Northern Territory, and into west Queensland. The Fierce Snake can also be found north of Lake Eyre and to the west of the split of the Murray River, Darling River and Murrumbidgee River. Fierce Snakes are known to live in holes, and feed on small rodents such as mice and rats. Despite its name, Fierce Snakes are not known to be particularly aggressive, but docile. They will strike if provoked, however, injecting their incomparably toxic venom.No fatalities have been attributed to this species, and all known bites have been to people who keep them in captivity or actively seek them out in the wild.
