Humans, in particular, eat frog legs as a delicacy. Frogs are used by humans for scientific study at virtually every stage of their life cycle. As eggs, frogs are used for the study of embryonic development. As tadpoles, they are used to study regeneration. As adults, they are used frequently in elementary biology courses.
Frogs are also exceptionally valuable in insect control.
