What are two common names for jumping, tailless amphibia?

When considering the diverse world of amphibians, two familiar names often come to mind for those tailless creatures known for their impressive leaping abilities. These are frogs and toads, both belonging to the order Anura, which literally means "without a tail". While often used interchangeably in casual conversation, these terms highlight some general differences in appearance and habitat, though it's important to remember that all toads are technically a type of frog, but not all frogs are toads.

Typically, frogs are characterized by their smooth, moist, and often slimy skin, which helps them absorb water and oxygen, making them well-suited for aquatic or semi-aquatic environments. They possess long, powerful hind legs designed for jumping great distances and swimming. Toads, on the other hand, usually have thicker, drier, and warty or bumpy skin, which allows them to live further away from water in more terrestrial habitats. Their legs are generally shorter and more adapted for walking or making smaller hops rather than long leaps.

Beyond these common distinctions, both frogs and toads play crucial roles in their ecosystems. They undergo a fascinating life cycle, typically starting as aquatic tadpoles before metamorphosing into their adult forms. Many species are indicator species, meaning their health reflects the health of their environment, as their permeable skin makes them sensitive to pollution and environmental changes. From the tiny, brightly colored poison dart frogs to the enormous Goliath frog, these amphibians showcase incredible diversity in size, color, and behavior across nearly every continent.
