No, a frog is not a reptile; it is classified as an amphibian. Frogs have moist, permeable skin and typically undergo metamorphosis from an aquatic tadpole to a terrestrial adult, unlike reptiles which have dry, scaly skin and do not experience metamorphosis. Frogs belong to the class Amphibia and the order Anura, whereas reptiles belong to the class Reptilia.
A frog's biological classification is: Kingdom Animalia, Phylum Chordata, Class Amphibia, and Order Anura, which translates to 'without tail'.
Common examples of amphibians include frogs and toads (order Anura), salamanders and newts (order Caudata or Urodela), and caecilians (order Gymnophiona or Apoda), which are legless, worm-like amphibians.
Frogs undergo a lifecycle involving metamorphosis, starting as aquatic tadpoles that develop into terrestrial adults, whereas reptiles have direct development where young resemble miniature adults and do not undergo metamorphosis.
