Rana is a genus of frogs commonly known as true frogs. They are found in various habitats, including ponds, lakes, and wetlands, across North America, Europe, and Asia. Rana species are characterized by their smooth skin, long legs, and strong jumping abilities, which help them evade predators. Many species within the Rana genus are important indicators of environmental health. They play a crucial role in ecosystems as both predators and prey. Some well-known species include the Rana catesbeiana (bullfrog) and Rana pipiens (Northern leopard frog), each exhibiting unique behaviors and adaptations to their environments.
