Why Are Spiders Venomous?
WouterSpiders are classified as venomous or non-venomous. A venomous spider injects its venom into its prey. The venom is a mixture of toxic chemicals. The effects of spider venom vary depending on the species of spider and the health of the bitten person.
There are 25 spider species that produce venom that is capable of causing illness in humans. However, the majority of the time, these venomous spiders do not harm humans. Some people may have a mild allergic reaction to venomous snakes or spiders.
A black widow spider is the most venomous of all spiders in North America. A bite from this spider can result in neurological damage, delirium, and death.
In addition to their venomous powers, spiders are very important predators. They help keep insect populations in check. They feed on smaller insects, and some species even liquefy their prey. They also use silk to wrap their prey for easier transportation to the nest.
In fact, the number of fatalities from spider bites is fairly low. Nevertheless, the presence of venomous spiders in indoor environments can pose a serious danger to indoor workers.
The most common symptoms of a spider bite are pain. The pain can be mild, like that of a bee sting, or severe, similar to that of a severe pinprick. The symptoms can include abdominal muscle cramps, pyrexia, and hypertension. In children, these symptoms are sometimes accompanied by distress.
The amount of venom injected depends on the site of the bite, the quantity of venom, and how long the fangs are in the tissues. Some of the more dangerous spiders, such as the Australian Hadronyche, can produce a large amount of pain.
