Little is known about the longevity of frogs and toads in the wild, but some can live for many years. Skeletochronology is a method of examining bones to determine age. Using this method, the ages of mountain yellow-legged frogs (Rana muscosa) were studied, the phalanges of the toes showing seasonal lines where growth slows in winter.
The frogs are large, have powerful leaps, and inevitably escape after which they may wreak havoc among the native frog population. [49] Countries that export bullfrog legs include the Netherlands, Belgium, Mexico, Bangladesh, Japan, China, Taiwan, and Indonesia. Most of these frogs are caught from the wild, but some are captive-reared.
American green tree frogs prefer to live in open canopy forests with a permanent water source and filled with plentiful vegetation. The species is found in both natural and settled environments, often being sighted in backyards with ponds, in garages or garden structures.
The true frogs vary greatly in size, ranging from small—such as the wood frog (Lithobates sylvatica)—to large. Many of the true frogs are aquatic or live close to water. Most species lay their eggs in the water and go through a tadpole stage. However, as in most families of frogs, there is large variation of habitat within the
The desert rain frog is mostly found on a small strip of land about 10 kilometres (6.2 mi) wide along the coast of Namibia and South Africa below the Congo basin. [8] The small area of sand dunes often gets a lot of fog, which supplies moisture in an otherwise arid and dry region.
Their digit tips are expanded, allowing them to climb, thus allowing most to live in elevated areas along forest streams, such as trees and shrubs. [8] Glass frogs are similar in appearance to some green frogs of the genus Eleutherodactylus and to some tree frogs of the family Hylidae. However, hylid tree frogs have eyes that face to the side ...
The African bullfrog is an exotic pet in many countries around the world. Animals sold are generally bred in captivity. Pet African bullfrogs may live for 35 years in captivity. [5] As pets, African bullfrogs are considered to be easygoing and low-maintenance in terms of their care. [20] It is considered a delicacy in Namibia. [21]
