The Order Anura includes frogs and toads, characterized by their tailless bodies, long hind legs, and webbed feet adapted for jumping and swimming. Anurans undergo metamorphosis, hatching from aquatic eggs into tadpoles before developing into adults. They are mostly carnivorous, feeding on insects and small invertebrates, and are found in a wide range of habitats worldwide. Anurans play important ecological roles as both predators and prey and are sensitive indicators of environmental health.
