Frogs And Toads: Order Anura
Frogs and toads are amphibians in order Anura. Amphibian Species of the World currently lists more than 8,000 living anuran species, making frogs and toads the largest living amphibian order.
What Frogs And Toads Are
Frogs and toads are anurans: amphibians in order Anura. Adults are tailless, usually have powerful hind legs, and often move between water and land across the life cycle.
The frog-versus-toad split is mostly ordinary language. True toads are in family Bufonidae, but many animals called toads are still frogs in the broader anuran sense, and some frogs look or live much like toads.
Life Cycle
The familiar pattern begins with eggs in water, followed by aquatic tadpoles and metamorphosis into froglets or toadlets. That pattern is common, but it is not universal.
Some species lay eggs on leaves, in foam nests, in burrows, or in tiny water pockets. Others skip the free-swimming tadpole stage and hatch as miniature frogs. Anura is diverse enough that species-level details always matter.
Major Groups
Frogs and toads include true frogs, tree frogs, true toads, narrow-mouthed frogs, poison frogs, glass frogs, spadefoots, rain frogs, and many other families. Each group has its own anatomy, habitat, calls, reproduction, and conservation issues.
True frogs often use ponds and wetlands, tree frogs climb vegetation, true toads tend to have dry-looking warty skin and parotoid glands, and poison frogs include small tropical species with diet-linked alkaloid defenses.
Ecology
Adult frogs and toads eat insects and other small animals, while tadpoles often graze algae, filter organic material, or feed in species-specific ways. They also feed birds, snakes, fish, mammals, larger frogs, and many invertebrate predators.
Because amphibian skin is permeable and many species rely on clean water, frogs and toads can respond quickly to habitat loss, disease, pollution, drought, and climate stress.
Conservation
Frogs and toads face severe global pressure from wetland loss, chytrid disease, ranaviruses, pollution, invasive species, pet trade, climate shifts, and road mortality. The right action depends on the species and location.
Public best practices are simple: protect clean water, keep native vegetation around ponds, avoid pesticides near amphibian habitat, do not move spawn or animals between sites, and never release pets outdoors.
