Anurans are a group of amphibians that include frogs and toads. They are characterized by their short bodies, long hind legs, and the absence of a tail in adults. Anurans are found in a variety of habitats, including freshwater environments, forests, and grasslands. They play important roles in ecosystems as both predators and prey. Anurans undergo a life cycle that includes a larval stage, commonly known as tadpoles, which are aquatic and breathe through gills. As they mature, they undergo metamorphosis, developing lungs and limbs for life on land. This unique transformation is a key feature of the amphibian life cycle.
