Today we can find various snake species in stages of this hypothesized development. There are the highly efficient envenoming machines - like the rattlesnakes - with large capacity venom storage, hollow fangs that swing into position immediately before the snake bites, and spare fangs ready to replace those damaged or lost.
Their fangs rarely have enough venom to kill a human but commonly cause painful swelling and discoloration. ... Garter snakes can bite or strike humans if they feel threatened. Small garter snakes ...
The SC LD 50 value is 0.4 mg/kg [89] and the venom yield per bite can range anywhere from 70–236 mg. [90] Unlike other snakes that flee from approaching humans crashing through the undergrowth, common death adders are more likely to sit tight and risk being stepped on, making them more dangerous to the unwary bushwalker. They are said to be ...
Marsh and Whaler (1984) wrote that 35 mg (1/30 of the average venom yield) would be enough to kill a man of 70 kilograms (150 lb). [5] Branch (1992) suggested that 90–100 mg would be fatal in humans. In humans, a bite from a Gaboon viper causes rapid and conspicuous swelling, intense pain, severe shock, and local blistering.
The evolutionary history of venomous snakes can be traced back to as far as 28 million years ago. [1] Snake venom is modified saliva used for prey immobilization and self-defense and is usually delivered through highly specialized teeth, hollow fangs, directly into the bloodstream or tissue of the target.
