Snake venom is a highly toxic saliva [1] containing zootoxins that facilitates in the immobilization and digestion of prey. This also provides defense against threats. Snake venom is usually injected by unique fangs during a bite, though some species are also able to spit venom. [2]
Average venom yield per bite is 37 mg and a maximum yield of 97 mg. [164] Bites from red-bellied black snake are rarely life-threatening due to the snake usually choosing to inject little venom toxin, but are still in need of immediate medical attention. Rate of envenomation is 40–60%, but the untreated mortality rate is less than 1%.

The eastern brown snake yields an average of under 5 mg of venom per milking, less than other dangerous Australian snakes. [65] The volume of venom produced is largely dependent on the size of the snake, with larger snakes producing more venom; Queensland eastern brown snakes produced over triple the average amount of venom (11 mg vs 3 mg) than ...
