Spiders are air-breathing arthropods that have eight legs and chelicerae with fangs able to inject venom.Their scientific name is order Araneae.They are the largest order of arachnids.This order ranks seventh in total species diversity among all orders of organisms.Spiders are found worldwide on every continent except for Antarctica, as no animal can servive there.If anyone can then the spider would be must.
They have become established in nearly every habitat with the exceptions of air and sea colonization.In a study of July 2019, at least 48,200 spider species, and 120 families have been recorded by taxonomists.However, there has been dissension within the scientific community as to how all these families should be classified, as evidenced by the over 20 different classifications that have been proposed since 1900.So you can see this is a long year process but they are adding new classes day by day.
This eight legged creature is very clam yet many men and women get frightened after seeing them.These animal can produce thread and it comes out from their abdomen.
