    How many species of amphibians are there in the world?

    The three modern orders of amphibians are Anura (the frogs and toads), Urodela (the salamanders), and Apoda (the caecilians). The number of known amphibian species is approximately 7,000, of which nearly 90% are frogs.

    Do all reptiles have lungs?

    The skin of reptiles is dry and scaly, so they can live in arid locations (although many do not). However, they cannot use their skin as an organ of gas exchange. Reptiles depend entirely on their lungs for this. Their lungs are considerably more efficient than those of amphibians.

    Are Penguins a bird or mammal?

    Like other birds, penguins have feathers. Penguins are fish, mammals, or amphibians because they live in water, on land, or both. Penguins are birds, even though they spend time on land and in water. Their motion in the water more closely resembles flying than the swimming motion used by other animals.

    In accordance with the Linnaeus method, scientists classify the animals, as they do the plants, on the basis of shared physical characteristics. They place them in a hierarchy of groupings, beginning with the kingdom animalia and proceeding through phyla, classes, orders, families, genera and species.
