How is the digestive system of a tadpole different than a frog's?

Tadpoles have a herbivorous (plant-based) diet and frogs have a carnivorous (animal-based) diet, and so during metamorphosis, some dramatic changes occur in the digestive tract. Herbivorous animals generally have longer and more coiled small intestines than carnivorous animals, because plant-based diets require more time in the digestive tract than animal based diets. In typical fashion, the herbivorous tadpole small intestine can be up to 10 times longer and much more coiled than the carnivorous frog small intestine. The stomach of the frog becomes more structurally complex after metamorphosis, with more folding
