A frog is a member of a diverse and largely semiaquatic group of short-bodied, tailless amphibians belonging to the order Anura. Frogs are vertebrates characterized by their stout bodies, protruding eyes, no tails, and limbs adapted for jumping and swimming. They typically have smooth, moist skin and webbed hind feet, which aid in locomotion both on land and in water
. Frogs are cold-blooded animals that live part of their lives in water and part on land. They are found worldwide except Antarctica, with the greatest species diversity in tropical rainforests and wetlands. Their skin can be camouflaged or brightly colored to warn predators of toxicity, and it plays a role in respiration, allowing them to absorb oxygen through their moist skin
. Frogs undergo a life cycle starting from eggs laid in water, which hatch into aquatic larvae called tadpoles. Tadpoles have tails and gills and later metamorphose into adult frogs, losing their tails and developing lungs for breathing air. Adult frogs are mostly carnivorous, feeding on insects and other small animals, and they capture prey with their long, sticky tongues
. In summary, frogs are amphibians with unique adaptations for a dual life in water and on land, notable for their jumping abilities, vocalizations, and complex life cycle involving metamorphosis from tadpoles to adults
