Did you know that as the largest order of arachnids, there are between 40,000 to 50,000 known spider species in the world. While spiders vary in size and color, they are air-breathing arthropods that share many common characteristics: an exoskeleton, which they molt or shed as they grow; eight jointed legs in four pairs; and segmented bodies covered in hair so fine it's not always visible.

​

Most spiders can build webs from silk-spinning structures called spinnerets located at the rear of their bodies. Spider silk is extremely strong and sticky. They do not have jaws to eat solid food, but instead have chelicerae or fangs that inject venom into their prey, which liquefies their meals.

Spiders do not have antennae, but they do have four pairs of eyes. Spiders also have an advanced central nervous system, enabling them to sense danger. No wonder you can’t sneak up on them!

In the spider world, the female spider dominates. Female spiders are usually larger than males and may be stronger and more poisonous. Some species of female spiders will kill and eat the male after mating.
