Why are amphibians omnivores but not herbivores?

There are some omnivorous amphibians, but the majority of amphibians are carnivores. Why? We really don’t know. It just worked out that way. Perhaps the niches that amphibians fill are specialized ones, and there aren’t really any ‘openings’ for an amphibian herbivore.
