Necrosis and snake bites

What type of snakes cause these bites?

Death adders and Gaboon vipers are most commonly known for these types of wounds. Death adders live in Australia, whereas Gaboon vipers are found in Africa in the rainforest areas. Other snakes that also cause necrosis are:

What is Necrosis?

Necrosis is when premature cells or tissue dies due to a Snake bite, other injury, lack of blood flow, or bacteral infection. bacteral infections that cause this are mostly Clostridium Perfringens, Streptococcus pyogenes, and Staphylococcus aureus. The science behind Necrosis is pretty interesting, for instance toxic production: whenever bacteria such as the ones listed enters the body, they release toxins and enzymes that basically break down the tissue, for example Streptococcus pyogenes produces exotoxins that cause cell damage, while Clostridium perfringens produces enzymes like collagenase and hyaluronidase, which weaken the tissue (like collagen and hyaluronic acid), allowing the bacteria to spread way faster and easily.

there is also Tissue death, when infection gets more and more severe and the tissue starts to die because of the lack of oxygen (also called hypoxia), the tissue becomes "necrotic", which means it starts to rot. Think of it as if you tie a rubberband too tightly on your wrist and leave it there for several hours/days, oxygen isn't able to reach the rest of your hand therefore the those cells start to die.

Probability Theory

Introduction

If a person were to randomly teleport anywhere on Earth, several factors would determine their death. These include whether they land on water or land, which continent they appear on, and their chances of survival if dropped from a random height. This essay will analyze these probabilities and assess the likelihood of survival given the conditions of such an event.

Probability of Landing on Water vs. Land

Earth is covered by approximately 71% water and 29% land. This means that the probability of randomly teleporting into a body of water is 71%, while the probability of landing on solid ground is 29%. If the teleportation includes oceans, seas, rivers, and lakes, then the vast majority of water landings will occur in the open ocean. Large lakes and rivers make up only a small percentage of the total water surface, meaning the probability of landing in a large body of inland water (rather than the ocean) is relatively low.

Probability of Landing on Each Continent

Continent Surface Area (million kmĀ²) Probability of Landing
Asia 44.58 29.8%
Africa 30.37 20.4%
North America 24.71 16.6%
South America 17.84 12.0%
Antarctica 14.2 9.5%
Europe 10.18 6.8%
Australia 8.56 5.7%

Probability of Landing in a Cave

Since caves cover only a fraction of Earth's land surface, the probability of teleporting directly into a cave is much lower. Estimates suggest that about 10% of land has significant cave systems. Therefore, the probability of randomly appearing in a cave is: 0.29 x 0.10 = 2.9% This means there is a 2.9% chance of landing in a cave upon teleportation.

Survival Chances When Teleporting to Land

One of the greatest dangers of random teleportation is the height at which a person appears. If the teleportation occurs anywhere between ground level and the stratosphere (~50 km / 164,000 ft), survival becomes a major concern.

Given these conditions, the estimated survival rate for falls onto land is only 2% (0.02 probability). Since there is a 29% chance of landing on land, the combined probability of landing on land and surviving is: 0.29 x 0.02 = 0.58%
