The fangs sink into the prey and a few milligrams of venom flows out. Sometimes,the venom just paralyzes the spider's prey. Many spider wrap up their dead or paralyzed victim in silk and then carry it to their home. However,spiders don't eat their prey like humans do. Spiders inject digestive enzymes into the prey. This is like an acid which turns the inside of the prey into liquid. Fanally,the spider drinks the internal parts of its prey just like a milkshake.
