Description : A toad sitting on a Lotus leaf laying eggs just below the bulbous pods of a Water Hyacinth plant. Toad refers to a number of species of amphibians. A distinction is often made between frogs and toads by their appearance, prompted by the convergent adaptation among so-called toads to dry environments, which often entails a brown skin for camouflage which is also dry and leathery for better water retention. Many so-called toads also burrow, which requires further adaptations. However, these adaptations merely reflect the environment a species has adapted to, and are not reliable indicators of its ancestry. Since taxonomy reflects only evolutionary relationships, any distinction between frogs and toads is irrelevant to their classification. Nepal.
