Some drop webs on their prey like nets. Other spiders jump on their prey, and others trap it. Most spiders eat insects, but some larger spiders eat frogs and birds. Spiders use many ways to catch, eat, and digest their prey. Spiders do not chew their food, they digest differently than other animals.
First spiders hold their prey with their fangs.
Then they bite their prey with poison, and wait for it to die. Next the spiders inject their prey with enzymes to dissolve the prey from the inside out. Then they slurp up the slimy remains. When spiders move they just pump blood into their legs. Then they remove blood from their front legs, which drags their back legs forward.
