“It’s like being shot or walking over hot coals with a rusty nail stuck in your foot…” 10 of the world’s most painful reptile stings

Pain is subjective, and although most stings are a real inconvenience, there are quite a few that can stop you from tearing up in your tracks, cursing loudly, and gnashing your teeth, he says. Richard Jones.

What is a sting?

A sting is not just a negative, sharp-headed blow; The solid, hollow stinger (or fang) is the carrier for obtaining liquid venom from a storage reservoir as deep under the skin and into the body as the moment will permit. There is usually an active pump, either pressing on the sac, or at the base of the hollow sting tube.

Toxins usually contain a combination of active ingredients: protein-degrading polypeptide enzymes that rupture and destroy meat cells; Histamines increase blood flow, which pushes the toxin into the body, causing swelling and redness. Neurotransmitters confuse and overstimulate the nerves, leading to a stabbing or burning sensation, but also throbbing and numbness. The poison is remarkably toxic. Exact measures are few, but a single wasp sting injects about 15 micrograms of venom (roughly 1/65,000 of a gram). This is very painful. Multiple stings cumulatively add pain.

What is the benefit of poison?

In nature, venom has two purposes: to subdue prey and defend against attack. Fortunately, no stinging animal has yet evolved to target humans as potential food, but there are plenty of animals that need their powerful stings to keep us away, because we are too dangerous a species for them. Others, thanks to some evolutionary luck, have toxins that target other organisms, but are nonetheless extremely potent in our hypersensitive skin.

Most stings can be relieved after a few moments of mild pain, but anaphylactic shock can be fatal. This is an extremely rare condition where an individual’s immune response reacts catastrophically to an injection of venom, releasing a cascade of histamine into the body and other inflammatory chemicals. Untreated, it can lead to shortness of breath, low blood pressure, interference with the heart muscles, and internal bleeding. Similar responses can be caused by peanut and penicillin allergies, and susceptible individuals usually carry an adrenaline medication to self-inject adrenaline to counteract the effects.

Bullet ant

Native to the rainforests of Central and South America, the sting of this large (20 mm) ant has been likened to being shot (hence its name). bullet ants) Or walking over hot coals with a rusty nail in your foot. Small colonies of a few hundred individuals use their stings to defend their nests against predators, as well as to kill small insect prey.

Tarantula hawk wasp

The very numerous species in this wasp family specialize in catching and immobilizing spiders to store a small nest cache in which a single egg is laid. The wasp larva then feeds on fresh spiders that are still alive but immobile. They often catch and subdue prey much larger than themselves, dragging it back into the nest burrow rather than being able to fly with it, and they have evolved powerful toxins to immobilize a spider that may fight back in a dangerous manner as if its life depended on it.

The largest tropical and subtropical species have stings long enough and strong enough to penetrate human skin and can inflict a painful blow. This usually happens by accident because they are large, black or strongly colored insects with heavily clouded wings, making them look very sinister – not the kind of cute insect you might willingly pick up between your finger and thumb.

Honey bees

Although they are everyone’s favorite insect, Honey bees They can inflict an extremely painful bite, and because of the social structure of their colonies, stings can be multiple and very dangerous. Although they evolved from wasps, honeybees now only need their stings for defense – against all manner of animals intent on attacking their honey stores and brood of succulent larvae.

They also defend their hives from unsuspecting humans who venture too close to them. The first to sting is often killed, as it is wiped off with a quick sweep of the hand, but the barbed stinger means that the point of the needle, venom sac and venom delivery device remain attached to the skin, still delivering venom. That bee dies, but the sting releases a telltale pheromone scent that effectively marks you as the enemy.

This recruits more bees to attack, but when they are killed and eviscerated by their stings, more alarm scent is triggered and only a rapid exit away from the hive will stop the attack. Ten stings and you might feel short of breath and a little nauseous, and you’ll definitely need to sit down and have a cup of tea.

One hundred bites and you should seek immediate medical attention. There is no antitoxin, but dialysis can remove toxins before they begin to cause damage to the organs of the heart, liver, and kidneys. A thousand bites is where the deaths start, but such events are not at all uncommon.

Social wasps

Wasps use their stings to kill insect prey to feed on their larvae in the nest, but they also need them to defend their protein-rich colonies against major dangers such as badgers, the misnamed honey badger (rattle) and the honey buzzard, which are more likely to seek out tasty wasp larvae than honeybee combs.

Just like honeybees, killing a wasp gives off an airborne danger signal that drives the nest’s occupants crazy. With approximately 10,000 workers in the nest at the height of summer, they form a well-organized army, ready to make a suicidal attack on behalf of their colony.

Paradoxically, severely infected wasps, with only a hundred or two individuals in the nest, are much more docile and less inclined to sacrifice themselves by attacking a clumsy human.

Back saddle caterpillar, acharya stimulants

Looking like a brightly colored Lego model of a caterpillar, this is not a toy that can be picked up casually for closer inspection. It is completely covered with large tufts of long spines. These spines are hollow and easily break into the skin, releasing the stinging venom inside.

They cause a painful rash, and can cause swelling around the affected area, nausea, shortness of breath, and migraines. This species is widely distributed in eastern North America and Mexico. The cocoon, in which the cocoon is formed, incorporates the same stinging hairs into the silk, and causes similar problems, but the rather dull adult moth is completely normal and harmless.

Arizona bark scorpion, Centruroides culpturatus

All scorpions have a sting in the tail, thus killing prey they catch with their pierced claws. There is a bit of folklore surrounding the size of the claws – larger pincers indicate a strong crushing grip so they need less of a powerful bite, but smaller pincers need more of a chemical boost so are stronger than the venom.

In fact, this is all a bit fictional. However, this species has gained a reputation as the most venomous scorpion in North America, and although deaths are very few (perhaps two in the last half-century), the pain is considered severe and an antivenom has been developed.

Velvet ants, family Mutilidae

Not ants, but certainly covered in a velvety layer of hair, these strange insects are wasps that lay their eggs in bumblebee nests, where the larvae feed on the host’s brood.

The females are wingless and furry, but the males look like thin black wasps. Females are unlikely to need to sting any bumblebees when they invade nests, but they inherited their venom from their wasp-like ancestors anyway.

Perhaps because of their cute appearance they may be picked up by the unwary, who then get a strong sting for their mistake. In North America they are sometimes called cow killers, although the exact number of cow deaths resulting from their stings seems to still hover around the zero mark each year.

Black widow spider, Latrodectus family

Most spiders have venom in their fangs, which is, ultimately, how they kill their insect prey. But very few of them have fangs long enough, strong enough, or sharp enough to pierce human dermis.

It is true that many black widow species found in warmer parts of the globe can inflict a painful sting if given the opportunity, but this is usually described as resembling a nasty wasp sting. This may be because black widows are relatively small spiders, making it surprising that they would be able to deliver a large bite if handled unwisely, but this has led to an unparalleled reputation.

This doesn’t help in a misogynistic world, where it is the females (usually much larger than males) that have longer jaws, larger venom sacs, and more painful bites.
