There are more than 40,000 spider species across the world. All spiders are arthropods. They have 8 legs, normally 4 pairs of eyes, and no antenna, which sets them aside from insects.
Spiders are carnivorous predators who can only take in liquid food. Their venom enables them to change their prey into a liquid substance they can eat.
Spiders produce silk, an elastic, adhesive material used to spin their webs. To date, no man-made material has ever matched the strength and flexibility of spider silk. Spiders spin their webs to catch their main food sources: insects and bugs.
Moisture-loving spiders can be found in crawlspaces and basements. Others prefer dry, warm areas like corners, attics, and vents.
