Froglet (young frog, order Anura) standing on vegetation. Froglets are the intermediary stage of metamorphosis from a tadpole to an adult frog. The near-absence of a tail, and its ability to breathe outside of water show that this froglet has nearly completed its metamorphosis into an adult. Metamorphosis describes a range of physiological changes that allow anurans to transition from fully aquatic to amphibious.
