Order Anura
Phylum: Chordata
Subphylum: Vertebrata
Class: Amphibian
Order: Anura (Frogs and Toads)
Species in this order are characterized by the lack of a tail, strong hind legs used for jumping and an aquatic larval stage. The larval stage of frogs and toads starts with small tadpoles hatched from eggs in water where the larva will feed on algae.

Order: Anura (Frogs and Toads)
Species in this order are characterized by the lack of a tail, strong hind legs used for jumping and an aquatic larval stage. The larval stage of frogs and toads starts with small tadpoles hatched from eggs in water where the larva will feed on algae.
This order includes frogs and toads, where all toads are frogs, but not all frogs are toads. Frog diversity is most abundant in the tropics, but you can find frogs on all continents except Antarctica. Their biphasic lifestyle restricts their first stage of life to water until they metamorphose into adults. Amphibians are generally sensitive to changes in the environment because of permeable skin and unshelled eggs.
