<strong><a href=”https://animalsdetails.com/quiet-animals/”>Frog and Toad</a></strong>, (order Anura) Also known as <strong>anuran</strong> or <strong>salientian</strong>, amphibians belonging to the order Anura which due to their broad geographical distribution, are recognized by everyone in the world. <em>frog</em> refers to forms that have long legs, mucus-covered skins and long legs. <em>toad</em> can be used to describe many different tall, short-legged and strong species that are particularly rough skins. The term <em>toad</em> is used in such a variety that a single member of a family could be called a toad and another closely related member could be a frog. The more familiar members of family Bufonidae could be classified by their slang term “true toads.” In this article, <em>frog</em> is broadly applied to all members of order Anura and <em>toad</em> to those for whom it has been traditionally employed. There are approximately 7,300 species in the world of toads, frogs, and other living creatures.

From elementary school to university, frogs can be used to teach. One of the primary biology classes that many kids receive is through the rearing of the larvae, known as pollywogs or tadpoles in science classes. Students are taught about the anatomy of frogs and embryology during biology courses.

Frog legs are consumed by people around the globe. Toads can be used to control insects. A few South American Indians poison themselves with the secretions produced by certain species of frogs ( <em>see</em> poisonous frog). Biochemists are currently studying the health advantages of these poisonous chemicals. Biologists interested in evolution discovers numerous fascinating and sometimes perplexing problems when studying the frogs. One example is the drastic decline of various species of frogs in the second half of the 20th century. .

Every frog are identifiable, however they come in a variety of sizes as well as changes to their structure. Some frogs are extremely small; perhaps the smallest is the Brazilian <em>Psyllophryne didactyla</em> adults are 9.8 mm (0.4 inch) or shorter in length (with legs drawn in). However the West African goliath frog, <em>Conraua goliath</em> has a body length that is nearly 300 mm (12 inches). A variety of frogs and tads have silky, moist skins. Toads from the genus <em>Bufo</em> are known as “warty” amphibians, the skin being highly glandular and covered in tubercles (small nodules that are round). Numerous frogs in other families possess tubercular skins that appear rough this is a result of adaptation to less humid conditions. The Centrolenidae tropical American small arboreal (tree-dwelling frogs) have the opposite problem. The skin on their beneathside is thin enough that it is possible to see the viscera and heart by looking through their skin. The majority of species have gas exchange through the skin. This is the method of breathing through the skin to enhance the oxygen intake by their lungs. However, the <em>Barbourula Kalimantanensis</em> from Borneo can get all its oxygen from its skin.
