At the very center of the rain forest food web sit the top, or apex, predators. In most rainforests, these central slots are held by the big cats—tigers, leopards and jaguars—the big snakes, the big crocodilians and the largest birds of prey. But even among these apex creatures there is never a truce.ut spiders themselves can fall victim to insects in the form of wasps and army ants. And while it’s easy to imagine rain forest birds eating spiders, it is also true that at least one species of spider in the rainforest food web—the Goliath trantula—eats birds. (See a short video on the Goliath here .).
