The leading theory in frog deformities, this amazing video shows the cycle of heron eating deformed frog infested with parasitic worms that are easier prey, heron dropping it's waste (with worm eggs) in a pond, snails eating the waste including the eggs, the eggs hatching inside of the snail and going off into the water to infest another tadpole and begin the vicious life cycle of another malformed frog. © BBC Nature
