This is an edit for the article "Frogs"-- Section Life History, Life Cycle, Adults. The statement that begins paragraph 2 "Frogs are primary predators" is in error. It should state that "Frogs are secondary predators, because their diets often contain predatory insects,and may contain hydras, predatory crayfish, small predatory fish, and frogs and other predatory amphibians. (Food pyramids and food webs must include all life forms.) (Thorp, James H. and D. Christopher Rogers, Eds, 2010:  Field Guide to Freshwater Invertebrates of North America.)
