Many people believe spiders are insects. But they are wrong.
Spiders that are air-breathing arthropods typically characterized by an external skeleton, simple eyes, eight legs, a segmented body and fangs that inject venom. They use this venom while hunting or when in danger. With around 40,000 known species, they are very diverse in terms of size and colour. They weave silk webs that are elastic in nature and waterproof. A spider can live up to 2 years.
Contrary to the popular belief, not every spider is dangerous. Only about 2% are potentially harmful, the rest don’t pose a threat to humans and only attack in self-defence. A bite by a poisonous spider can cause pain, swelling, itching, nausea, and in severe cases, system failure resulting in death. The black widow and brown recluse contain powerful venom, enough to kill a human.
