Before antivenom was available 100% of bites were fatal. "The mulga snake has exceeded 1.3g of dry venom from a single milking," says Fry, whose passion for his subject has earned him the nickname "Venom Doc". Some species eat worms while others pick off fish. These strikingly beautiful snakes have a potent bite, and their fangs are longer than any other venomous snake in the world. The maximum wet venom yield is 200 mg. [54] In only a few detailed reports of human envenomation, massive swelling, which may lead to necrosis, had been described. A bunch of feathers will seem like they'd have more give, at least if the direction of the damage is in the direction of feather growth. 65% of human stinging cases are fatal without medical attention – although only 36 such fatalities have been recorded since 1670.
But even this seemingly precise measure is tricky to interpret, because not all venom is equal. But when it is threatened it can bite several times in quick succession, repeatedly delivering a full load of venom.

So with regards to getting a cut/injury in the first place I feel like birds have an advantage. Description: The Gaboon viper is a very heavily built snake, with males averaging a total length of 5ft(1.5m)and females averaging a total length of 5.5ft( 1.6m). According to Dr Bryan Fry of the University of Queensland in Brisbane, Australia, one of his local species produces more venom than any other. Cone snails are carnivores.
"For species of cone snail that hunt fish it is important to have a very fast-acting and powerful venom, because otherwise fish can easily escape from such a slow moving predator," says Dr Ronald Jenner of the Natural History Museum in London, UK. The snail launches one at an unsuspecting fish, whereupon it delivers a cocktail of toxins that target the nervous system.

Being slow-moving, they have shells that act like suits of armour, but they can also deploy venom when threatened. The Gaboon viper (Bitis gabonica)'s venom is extremely toxic for mammals.
Because of possible losses in activity which may occur during drying and storage it is suggested that care should be exercised in interpreting results of coagulation tests involving the use of dried venoms prepared under ill-defined conditions.

Scorpions paralyse their prey with their notorious sting. To take down their targets, cone snails have modified teeth called "radulae". However, yield is not the only way to measure how venomous a species is. The venom delivered in a single Taipan bite is enough to kill up to 12,000 guinea pigs. When cornered it displays its open mouth and hisses to warn off the threat. It hunts at night for worms, centipedes and other invertebrates. Not sure I think someone on this forum said that the study will be released in like a year or two. Intuitively I'd agree, but I'm open to being proven wrong. But the inland taipan lives in the remote deserts of central Australia and biologists describe it as reclusive. Yes, both were separated by about 4-5 million years. In any list of the world's most venomous animals, snakes often get top billing. It has a fearsome reputation due to its great size, long fangs, and high venom yield. Drying of freshly collected venom from our own snakes and storage of this material for 8 weeks at –27, 4, 20 and 50°C did not reduce its coagulant activity but storage of liquid venom for 7 hr at 50°C produced a rapid decline in activity.
Before antivenom was available 100% of bites were fatal. "The mulga snake has exceeded 1.3g of dry venom from a single milking," says Fry, whose passion for his subject has earned him the nickname "Venom Doc". Some species eat worms while others pick off fish. These strikingly beautiful snakes have a potent bite, and their fangs are longer than any other venomous snake in the world.
