HOW DO THE SPIDERS EAT?

Spiders don’t chew their food. When they get to the bug in their web, they bite it and inject venom. The venom either paralyzes or kills the bug. Then the venom turns the bug’s insides into liquid. While the venom is working, the spider wraps the bug in silk. She may drink the liquid( a mixture od digestive liquids) then, tie the little silk bundle to her web so she can snack later.

The majority of the spiders are predators, mostly preying on insects and on other spiders, although a few large species also take birds and lizards.predators Spiders use a wide range of strategies to capture prey: trapping it in sticky webs, lassoing it with sticky bolas, mimicking the prey to avoid detection, or running it down. Most detect prey mainly by sensing vibrations, but the active hunters have acute vision.lassoingbolas

8. Can spiders bite? Yes. Below the eyes on head end of a spider's cephalothorax are two small jaws (chelicerae) that end in fangs. Venom (poison) is produced in glands behind the jaws and empties along ducts in the fangs to paralyze or kill prey. Relatively few spiders bite people because they are not able to pierce the skin with their fangs. The majority of those spiders that can bite people have venom that is harmless to people. Two notable exceptions in the United States are the Brown Recluse, and the Black Widow.
