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 catsâtigers, leopards and jaguarsâthe 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 itâs easy to imagine rain forest birds eating spiders, it is also true that at least one species of spider in the rainforest food webâthe Goliath trantulaâeats birds. (See a short video on the Goliath here .).
Those that do the eating or hunting are called predators.. Examples of common predators include lions, bears and foxes. Those that are eaten or hunted are called prey.. Examples of prey animals include zebras, fish and rabbits. Of course, some animals can be considered both predators and prey. For example, a spider hunting for insects is a predator. If a lizard eats the spider, though, it becomes prey.
