The larger spiders, such as tarantulas can even occasionally capture small rodents, lizards, snakes, and birds. O nce a spider catches its prey it regurgitates digestive juices, or enzymes, into it. These enzymes start to break down the tissues of the prey into a nutrient liquid. The spider sucks up the nutrient broth into its mouth. Spiders are suctorial feeders and do not eat solid food.
Small spiders poke holes into their prey and suck out the juices through the holes.
Some of the larger spiders crush up their prey to eat. When they are done, all that is left is a little pellet of indigestible material. A s spiders eat, they start to grow. In order for a spider to grow, they have to periodically molt or shed their exoskeleton. A spider will stop feeding for several days when the molt is near.
