Frog is an amphibian mostly characterized by long hind legs, a short body, webbed digits, protruding eyes and the absence of a tail. Most frogs have a semi-aquatic lifestyle, but move easily on land by jumping or climbing. The lifespan of a frog depends on the species in question. Little is known about the longevity of frogs and toads in the wild, but some can live for many years. Generally, a frog's life span is between 7 and 24 years.

Skeletochronology is a method of examining bones to determine age. Captive frogs and toads have been recorded as living for up to 40 years, an age achieved by a European common toad (Bufo bufo). The cane toad (Bufo marinus) has been known to survive 24 years in captivity, and the American bullfrog (Rana catesbeiana) 14 years.

Other species which live to ripe old ages are:
Giant Toad (Bufo marinus): Age ranging between 7 and 24 years. Giant tod is also Known as The Cane Toad and Marine Toad. The Giant toad can also locate food using its sense of smell as well as identifying the prey by movement and vision. They eat plants, dog food and household refuse in addition to the normal prey of small rodents, reptiles, other amphibians and birds.
Green And Black Poison Dart Frog (Dendrobates auratus): Age ranging between 7 and 17 years. These frogs are formerly known as poison arrow frog. Indigenous use of their toxic secretions to poison the tips of blowdarts are the reason these amphibians are often called "dart frogs". Adult frogs lay their eggs in moist places and are generally found in tropical rainforests.
Oriental Fire-bellied Toad (Bombina orientalis): Age ranging between 11 and 14 years. Oriental Fire-bellied Toads are typically bright green in colour with black mottling on their dorsal regions but this colour can change according to their background scenery. They inhabit warm and humid forested regions.
Ornate Horned Frog (Ceratophrys ornata): Age ranging from 5 to 12 years. These are also known as the Argentine wide-mouthed frog or ornate pacman frog. They are well known for their fearless reputation.
