Rana
Leopard Frog (Rana)
Where found: Once abundant in North America and Canada, their population has declined in recent years because of pollution and deforestation. Leopard frogs are often used as environmental indicator species because of their heightened sensitivity to chemical pollutants found in the air and water.
Description: Leopard frogs, which are also called meadow frogs and grass frogs, are a collection of so-called true frog within the genus Rana. They are commonly used as dissection specimens in biology classrooms. Leopard frogs are recognized by their green or brown coloration with distinct light-edged dark spots across the back and white underside. They also have a characteristic line of raised glandular skin extending from each eye to the groin.
