Spiders can be found in garages, basements, attics, cabinets, sheds, gardens, woodpiles, in the garbage, under tree bark, and inside of homes. Spiders have four pairs of legs and fangs at the ends of their mouths to bite the prey and inject venom.
Tips
All spiders are predatory eight-legged creatures that have organs to spin silk at the back ends of their bodies.
Spiders all have the ability to bite with venom-injecting fangs to kill prey and nearly all of them are poisonous.
There are about 40,000 types of spiders in the world, living on every continent except Antarctica.
They’re not newbies: fossilized spiders have been found in Carboniferous rocks dating back 318million years.
Spiders have two body segments, the abdomen and the cephalothorax.
The spider’s jaws, called the chelicerae, are tipped with fangs, according to entomologists at the University of Kentucky.
These appendages are used to hold prey while the spider injects venom.
Behind the jaws are the labium and labrum, which work together to direct food into the spider’s mouth.
Between the chelicerae and the first pair of legs are the pedipalps, which look like tiny legs but are actually similar to antennae, and are used to sense objects the spider encounters
Most spiders have six or eight eyes, according to the University of Kentucky.
Some spiders can only see the difference between light and shadow.
A spider’s abdomen is where most of its important internal organs are located, such as the reproductive system, lungs, and digestive tract.
75 Facts about Spiders
Also on the abdomen are the spinnerets, through which a spider produces its silken web.
Some spiders use their webs to trap prey; others line their burrows with it.
Spiders are grouped according to the type of web they make
Groups include tangle-web spiders, orb-web spiders, funnel-web spiders, and nursery-web spiders.
