Most spiders and spider bites are harmless. However this distinction is important to make because venom is not necessarily poisonous.
But this phrase is not technically correctstrictly speaking most dangerous snakes are venomous.
Is venom more dangerous than poison. While some animals seem more dangerous than others there is really not much pointing to either poison or venom being more dangerous than the other. So it is not easy to find the most venomous. Its important to remember that spiders largely avoid humans.
The answer to the question of whether baby rattlesnakes are more dangerous than adults lies primarily on the snake-related side of the equation. Most spiders and spider bites are harmless. There are more than 40000 species of spiders in the world and only 12 of the 500 species that bite have venom.
Whats more even though its venom is certainly powerful enough to kill a human its small jaws and insufficient fangs mean it rarely bites anything much larger than a fish. The composition of the venom and the quantity of venom injected into the patient. They found that the amounts of venom measured were consistently and significantly greater from the larger greater than 66 cm in length versus the smaller less than 55cm snakes.
According to biologists the term venomous is applied to organisms that bite or sting to inject their toxins whereas the term poisonous applies to organisms that unload toxins when you eat them. Venomous black widow spider bites snake bites and jellyfish stings certainly sound more dangerous than contact poisons but in terms of worldwide exposure the more dangerous of the two is undoubtedly animal poison since it doesnt require animals to take an active role in the toxin delivery system. This means that very few snakes are truly poisonous.
Equally false to the myth about smaller Scorpions being more poisonous is. The more targeted the venom the more damage it can do. Would you rather be bitten by a venomous rattlesnake or touch a poisonous dart frog.
Is One More Dangerous. The presence of digestive enzymes in snake venom was once. Poisonous organisms release toxins when they are eaten or absorbed by touching the skin.
Rose Eveleth sheds light on the distinction between poison and venom and why you shouldnt treat either one like youve seen in the movies. Both venomous and poisonous animals produce a toxin that harms or kills another organism. In the discussion section they point out the volume differences as well as information from other sources that argue against the smaller is more dangerous theory.
While both of these animals are capable of doing some serious damage to the human body they deliver their dangerous toxins in different ways. Venom can be used as a defence against predators or to attack prey. Some of the various adaptations produced by this process include venom more toxic to specific prey in several lineages proteins that pre-digest prey as well as a method to track down prey after a bite.
The damage done by either is usually the same- a chemical reaction affecting the heart brain nervous system and other vital targets some more effectively and quickly than others but all doing the same thing- breaking. Scorpions like all organisms that bite or sting to inject toxins are actually venomous. There are more than 40000 species of spiders in the world and only 12 of the 500 species that bite have venom strong enough to harm humans.
And they usually only bite people as a defense like if you step on one hiding in your shoe. The pertinent snake factors for this question fall into two categories. And that is just fine.
