Spiders are air-breathing arthropods that have eight legs and fangs able to inject venom. There are at least 45,700 spider species and, although most spiders live for at most two years, tarantulas and other spiders can live up to 25 years in captivity. Spiders make silk in a combination of lightness, strength and elasticity that is superior to that of synthetic materials.
